Bob, isn't the KH low though? I know baking soda will
raise the KH -and pH will stablize at 8.4 - but I have no idea what baking soda will do to lower the pH. Seems like the buffering should also be addressed.

Sue, you don't need to tell me about the rain: it *tries" to screw with my
water chemistry, too. When the rain comes from "inland" over the phosphate mines, I've had my KH drop by 80 points in a few hours. But you've got a few problems going on he new pond, heavy rain, and that (expletive deleted) algae. a. At this point, I'd stop with the epsom salts and lime, as you're GH is getting high. Don't add any more until your GH drops by 50 points or so. I'd try to keep it in the 100-125 range. b. Keep adding the baking soda. I keep my KH in the 11-13 drop range (~200 to 230). I don't even test my pH any more unless I suspect a problem, because I know that my pH will be 8.2 AM and 8.4 PM, rock solid. BUT. . . your pond hasn't stabilized yet. It's still new. So until it stabilizes, you need to check the pH also, otherwise you won't know what's going on. c. You say "brown algae" - is it that stuff that floats to the top during the day and drops back down at night? If so, welcome to the world of cyanobacteria. I finally sent samples of my algae to a lab for diagnosis. This will be a whole OTHER topic of conversation! But let me know and we can work on that, too. Even if it's just plain ol' algae, it's a problem. At night, plants (all those potted ones you have and the algae) reverse photosynthesis and use up oxygen (instead of creating it, like they do during the day), and release CO2 (carbon dioxide), which is acid. That drops your pH. During the day, the plants create O2, which raises your pH. So, you have a yo-yo effect going here. Obviously, one of the best things you could do towards stabilizing the pH would be to get the algae problem under control, which is easier said than done. However, in the meantime, I suggest adding air to your pond with airstones or a good air manifold. It will serve a two-fold purpose: a) our water temps are HIGH during the day, and warm water carries less oxygen than cooler water, so it will make the fish more comfortable; and b) it will keep the oxygen levels higher at night, and reduce the pH swing. Besides, my fish like to swim through the bubbles: I think it tickles! Let me know if there's anything else I can help with. Lee "Sue Walsh" wrote in message om... Theron wrote in message . ..

Kathy, as Theron stated, Baking Soda is strange inasmuch as it will both
raise and lower pH to the 8.2-8.4 range. It will also raise your KH to a more respectable number, which will add the buffering you need to protect against pH crashes in heavy rains. Are you by any chance on well water? By the way, 9 is "getting" high, but is still a safe and respectable level. Don't lose any sleep over it: your fish and plants will do just fine.

I used to deal with it in my labs, but didn't understand all I knew about it. Thing is, the higher the Ph, the more baking soda will be needed. It could take a lot. Maybe it will give the fish fresh breath and white teeth. "Thanks for the Memories" Bob |
Lowering pH
Thanks, Lee for the advice. No to well water. This has been frustrating
for me because I've never had a pH/KH problem with any of our other ponds. This is a 3 month old pond in full sunlight. And when I say full.....I mean at least 9 hours of sun. We have a living gravel filter and lots of plants. My ongoing fights have been getting enough surface shade, using plants, and the pH/KH. We used a different stone for couping and my guess is that it is full of limestone (Laurel mountain stone). The pH this morning was 7.7 at 83o. Right now (3:45) it is 9.1 at 89o. The pond is 2400 gal. with a 3/4HP pump and because of water temp., I've added an air diffuser in the farthest corner. During the hottest time of the day, the fish either have disappeared in the hornwort in the deepest part of the pond or are riding the current from the waterfall. As soon as the sun gets off the pond, they all come out to stretch their fins. Something I don't understand is....Nedra mentioned that Rod recommended adding the BS over a three day period. I'm assuming that is for a gradual decrease/increase of the pH. If the fish are going thru a pH swing, like my situation, then why hassle with a gradual change, why not get the sucker lowered/increased over the course of a day? It couldn't be any worse then what they are going thru, anyway. Thanks again. Kathy "Lee Brouillet" wrote in message ...

I try to keep my KH up at a level similar to Lee's, and if it drops to about
6 or 8 drops, the pH is still rock solid, and I just dump in about 2/3 of a 10 pound box of baking soda in the 4000 gallon pond and 1/3 in the 2500 gallon pond. That is as close as I measure. I have to do this about once or twice a month. Cups are too small, unless you are initially trying to stabilize the pH, where you don't want to give a pH shock. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Nedra" wrote in message thlink.net...

Nedra,
Actually both you and Lee agree that I should keep up with the baking soda. So by your calculations I can add 1& 1/2 cups for my pond and still be safe for the fish. OK, I will do that 3 days running, between the rain drops (actually torrents & lightning strikes). Lee, Basically it's brown water that gets worse when stirred by rain, I can only see down about 8" maybe 10" into the pond. The liner, edges of the leaves and stems get covered with the brown stuff. The filter gets clogged in a few days and we need to keep cleaning it. It looks like dirty bropwn water, but the pond guy around here says its brown algae. Doesn't the waterfall do enough to add oxygen to the water, it comes in at a pretty good rate from the stream? I never see the fish up top looking for air. They do occasionally swim thru the waterfall. Had one in the skimmer yesterday, got it out and it seems to be OK, anyway to stop that happening again? Will Get the biofilter up and running and then just wait it out. It would be so nice to be able to see my fish where ever they are! Should I be doing 25% water changes in the pond at this point? I used to do it in the barrel garden, but I'm not sure if it would do any good here or just slow up the process of balancing. Thanks, Sue W "Nedra" wrote in message rthlink.net...

3 months is still a new pond, and my experience is that they have wild
swings. It's not good, but they do. The limestone (if indeed you have it in the pond) should not be a problem: it wants a pH of around 8. Above 8, and it just sits there. Below 8, and it slowly dissolves. But it's not a radical change. A gradual change in pH and KH is more desireable than an abrupt change. But you're correct: if it's already doing that anyway, what's the harm? Just get it in there and hope it starts to work. When I first dealt with "new pond syndrome", it took several weeks to settle down and find its median. Somewhere on another post I answered I mentioned the change of pH between AM and PM, linking it to the plants, reverse osmosis and all that stuff. CO2 is acid, which will drive pH down. In the day, the plants produce O2, driving the pH up. Baking Soda will give you enough buffer in the KH to hold against the CO2 enforced drop. You mention below that you also have an airstone going, which is good: it helps to provide the oxygen that the fish need in the higher water temps, and it helps to counterbalance the CO2 that the plants put out at night. For what its worth, I keep my KH ~ 200-225. At that range, the water/pH doesn't have much of a choice but to stabilize. And filters (mine is a bead type, but ALL filters) need the carbonate to feed the bio-bugs, which means the filter works more efficiently. It buffers against acid rain. It's a good thing. The fish need stability in the pH. Go for it. Lee "Jeff & Kathy Brown" wrote in message ... Thanks, Lee for the advice. No to well water.

Sue: Yes, the waterfall adds oxygen to the pond, depending on the drop. I
have 3 waterfalls, but the 2 that enter the pond are only a shallow drop, and don't add much in the way of surface disturbance. If you have a drop of 18" or so, you may be OK. However, extra O2 is *never* a bad idea. I'd place the airstone about 2/3 of the way from the waterfall: the airstone will ensure that the far end of the pond also is properly aerated. Your "brown algae" doesn't "quite" sound normal. New ponds usually grow nice green stuff, not brown stuff. Especially brown stuff that breaks loose and clogs the filter. Do you have any Koi Clay? Among its many benefits, it also acts as a floculant: it gathers the stuff floating in the water column and takes it to the bottom, leaving you with clear water. Considering that your water is pretty clouded, if you have some, I'd mix about 1/2 cup in a bucket of pond water, mix it up to disolve it, and pour it around the pond edges. Try to get it mixed in with the water. It will turn your pond gray for a few hours, but should clear over night. It may help, but it definitely won't hurt. Another thing you could try: replace your skimmer mat with a lingerie bag stuffed with netting, the kind you use for crafts (like coarse bridal veil). It will catch a lot of the "fines" that are going through it, which will also help clear your water. BE FOREWARNED: I have to clean mine twice a day, but my water's gin clear! Just take the bag somewhere where you can blast the blazes out of it with a water hose, then plunk it back in. If you've got what I think you have (cyanobacteria), it will be an on-going effort until the water cools again. It works in cycles; I'm on my third since Spring. As far as fish in the skimmer: I've got to tackle that one myself this weekend. My fish don't get trapped, but the go in looking for food and get stuck. I'm constantly finding scales they ripped off trying to get back out. The problem is, you can put anything over it that will block the water flow. But it has to be large enough to keep the fish out.

Hmmmmm, guess I'll start checking the pH of rain water.
I did notice a good drop in pH back when we were getting all that rain - not much lately - rain that is. Figured that was from the normal absorbtion of CO2.

Lowering pH
So you try to keep your KH in what range?
And you do this with Sodium Bicarbonate? Can you add too much bicarb? I ask these questions because it seems every time I put something in my pond, the lily pads get soft spots or something. It may be Muriate of Potash that causes this problem - I stopped using it for the present.

Lowering pH
I have a bead filter and a very heavy fish load, which is a bad combination
for KH. A bead filter isn't "happy" unless the KH is over 200; I keep mine (basically) in the 11-13 drop range, which is about 200-230 ppm. You can keep a stable pH at 8.3 (give or take a tenth!) with KH in the 150 range, and still have enough wiggle room for rains. Just check the KH after a good rain and bring the KH back up. Use regular baking soda (sodium bicarbonate), nothing fancy. You can get the generic stuff at the grocery store and it works just as good as Arm and Hammer. I won't say that you "can't" add too much, but the folks that import fish and are even more overstocked than *I* am routinely keep their KH at 400-500 to avoid crashes. It should have no affect on your lilies whatsoever. For that matter, the potash should have made the plants stronger, not weaker. Lily pads don't last much longer than 2 weeks or so anyway, depending on the "breed" of lily. Some last a goodly amount of time, and others are prolific, but short-lived. BTW, add about a cup per 1000 gallons of baking soda to your pond and measure the difference and adjust as necessary. Using that formula, I can raise my KH by one drop. If you have a skimmer box, you can just drop the whole cup in and walk away, but you must keep that concentration away from the fish. If you don't have a filter or something away from them, mix the BS in a bucket of pond water and splash it around the pond. Lee "Weldon Wallick" wrote in message ...

Sue: Yes, the waterfall adds oxygen to the pond, depending on the drop. If you have a drop of 18" or so, you may be OK. Actually, the waterfall is two tiered from the head pool into the stream with each drop about 9", then it travels the lenght of the stream 22', then it drops into the pond about 12". How big of an airstone are you talking, in the barrel all I had was a walnut sized one. Where do you get bigger ones? What type(size?) of air pump do you need to run the size you are recommending? I'd place the airstone about 2/3 of the way from the waterfall: the airstone will ensure that the far end of the pond also is properly aerated. I have a water spouting crane which leaks so badly that it can't be used. It is at that 2/3 locations that you referred to. I put it there to make sure water moved all around the pond, no dead spots. If I can get it fixed would that do the job for the extra oxygen? Your "brown algae" doesn't "quite" sound normal. New ponds usually grow nice green stuff, not brown stuff. Especially brown stuff that breaks loose and clogs the filter. It's like loose silt, really doesn't look like algae... Do you have any Koi Clay? No, on the Koi Clay. Where do we get it around here? Tampa, Hernando or Pasco county or on the internet? replace your skimmer mat with a lingerie bag stuffed with netting, the kind you use for crafts (like coarse bridal veil). This I can do easily. If you've got what I think you have (cyanobacteria), it will be an on-going effort until the water cools again. It works in cycles; I'm on my third since Spring. cyanobacteria?? I"ll have to look that up as I've never heard of that one, but that's par for the course, remember when I first filled the pond back in January I had red algae. Drained and redug it since then and glad it didn't appear when we refilled in May. Thanks Lee for all the good info...Sue W |

If you don't have Aquatic Ecosystem's catalog, you NEED it G! I can (and
have!) spend *hours* looking through it. They have a pretty extensive website, but it's a little hard to navigate. However, you can order the catalog from the http://www.aquaticeco.com You can find the airstones, pumps, and more stuff than you ever thought existed! They're over there around Apopka, so even "regular" UPS is "next-day" delivery for us'ns here in FL. Your water-spouting crane would help, but it's not as efficient as the airstone(s). It just *looks* nicer! If I remember during my search for info, there are over 40,000 different species of algae. I think at one time or another, most of them have found their way to my pond (long sigh . . .). And it's very difficult to get rid of: even dumping the pond and scrubbing everything doesn't get rid of it all. It hides in the plants, on your rock work, EVERYwhere. And all it needs is a few pieces to reestablish itself. That brownish, olive-green silty stuff could still be cyanobacteria. It comes in multiple forms, too. BTW, I've never heard of red algae except for the blooms in the Gulf, which are usually deadly. There's a fresh water version of it, too??? Sheesh . . . I've never been able to find Koi Clay locally. No one carries it. But get ahold of Gene Winstead at http://www.koivillage.com and he'll get some out to you. Check out his site (both commercial and personal): he has a lot of info.
