phosphates too high, need advice
here is a pic of my tank...you can't really see the hair algea from this
pic, but I thought i'd share it. http://idoneous.net/images/75_tank/tank.jpg "SlimFlem" wrote in message news:LNWta.759433$F1.96718@sccrnsc04...

I also think you water change schedule is seriously lacking. I do weekly 50% water changes on my high light tanks. You are only doing 10 gallons a week. You should be doing more along the lines of 35-40 gallons a week. What bulbs do you have in your lights? Are they the standard 50/50 bulbs that come with Coralife fixtures? 6500K (2) 10000K (2) How much, how often, and what are you feeding your fish? i feed once per day. i rotate between frozen brine and bloodworms, and tetra flake and pellets How many fish do you have in the tank? 2 large Angelfish (about 7 inches from top to bottom) 6 Clown Loaches ( all about middle finger size) 2 Rainbowfish (both about 4 inches) 6 Serpae 5 Red Eye 7 Zebra Danio 3 Otto 1 Whiptail Catfish Do you know what your tap water phosphates level is? The phosphates from my sink do not register. However, the phosphates in my tank still read off the chart. I am now confused. What would could them to go so high in my tank. I don't add anything to the tank besides what I have stated here. For as much light as you have over the tank your fertilizing regime really sucks. With this much light over the tank you really should be dosing nitrates, potassium, phosphates (unless your tap water is high in phosphates), iron, and traces. Also, I used to fertilize more heavily, but my plants were doing great so I cut it back a little. The plants I have, all Sag and Val are doing really good. There is only a very small amount of hair algea on some of them, not all. The hair algea is primarily on the root wood, and some rocks and a few tuffs growing in the Florite. You have fallen for a common mistake of placing a lot of light over a tank and thinking you are done. High light tanks require a lot of work. Do you have CO2 injection? With this light level CO2 injection is not a luxury it's a requirement. And DIY CO2 is not going to cut it. I was using DIY CO2, but after i had a herniated disc in my back about 2 months ago, I no longer am doing this since I can't really bend so much right now to get under the tank and set them up. I live by myself. If you will post your pH, kH, gH, and nitrate levels we will be able to give you more help. Algae growth is the symptom of something wrong with your tank, you need to treat the problem and not the symptom pH = slightly above 7.0, not much, just barely kH = 2 gH = 5 NO2 = 0.3 mg/l NO3 = less than 10ppm And believe me, I want to treat the problem, not the symptom. Thanks for the assistance. Hi, I have a 75 gallon planted tank and have recently started getting green hair algea growing on some plants and on some rocks. My plants are doing great. I have a Coralife compact flour light 4 x 65 I think it is. Well, I bought a Tetra Phosphate test kit and the blue is so dark it's off the scale. I don't understand this. I do 2 water changes a week. Each one is about 5 gallons. I use some of the Florish products weekly. for filters i have an Eheim Pro canister and a Magnum 350 that I use to run different filter media in. I usually use Purigen. I get good effects from it. The only other thing I have used is some stuff called "Instant Amazon". It says it doesn't support algea growth, but I am starting to think otherwise. I have stopped using it until I stop the algea. Oh yeah, my lights are on timers and I had the lights running about 13 hours a day. I know that is probably too much. I have reset the timers to about 10 hours a day. How does that sound? Why do you think my phosphates are up? I did about a 20% water change today with water that airated overnight, but the phosphate levels still read as high. Do you think the reading could be false? I also have a SeaChem PO4 test kit. I take a test with that one and see what it indicates. thanks for any advice and reading all my questions. Semper Fi!
