Need green water help
Betcha you've heard that question before...but I did read the FAQ.
Unfortunately, I still have green water and I thought I'd done everything natural to cure it. I've finally got 75% of the surface of my 3 barrels shaded with water hyacinth, water lettuce, and duckweed. The WH has almost doubled in 2 weeks. Oxygenators are growing well, with about 4 bunches in each barrel. I've got marginals in each barrel too now - some are just getting started but the Acorus, fiber optic grass, umbrella palm and canna lily are growing well. I also started some watercress and it seems to be taking hold. My newly planted Iris are breaking the surface now, and pickerel is getting close. I can't see the water lily in the green water so no idea whether it's growing or not. I've tested the water and there's no ammonia, nitrite, or even nitrate. pH is 7.4. I don't have a phosphate test. It seems I have enough biofiltration. I have two of these 4" strainers http://www.calpump.com/productsub.as...0T&category=10 on my pump intake covered with their thick foam prefilters and filled with bioballs. Actually one is half Chemi Pure and half bioballs at the moment. I have about 65 gallons of water housing 3 2" shubunkins, 3 white clouds, 2 gambusia, and some ramshorn snails. The smaller fish have been in the pond for a total of 10 weeks with the first shubie added a little over a month ago. The plants have apparantly finally sucked all the nitrates out of the water, according to plan. The nitrate has dropped from about 5-7 ppm to zero since I added the WH and duckweed. I've also been fertilizing regularly with iron, trace elements, and potash the way I do fishtanks to help the plants out. Even the green fuzz has slowed down to the point that the fish and snails are keeping it lawnmowed. Bu the green water keeps right on going. So, I have shaded water, no nitrates, a TON of now nitrogen-starved plantlife, hopefully adequte filtration and the water is still so green and murky I can't see deeper than about 6". Fish? What fish? I'm at a loss. Chemicals are not an option as I intend to eat my watercress, and the cost of a UV unit is currently prohibitive. Do I need more filtration, even though there's no ammonia or nitrite? Do I leave things alone and wait now that nitrates are zero? Do I add nitrate in case the plants are starved for it and can't outcompete the algae? Should I try a flocculating agent? Help! -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |
I have seen good and bad come out of useing a floculate. Some require
light for so many hours and so many ours of continuous filtration and lots of filter cleaning. I know you said your not wanting to use chemicals, but aluminum sulphate is not harmfull. I am a a true believer in it, in the form of Baraclear-80.....If it can turn my natural pond into a very good looking and nice water quality like it did I am sure it would work for a liner or barrel setup as well. I had thought my water was nice and clear late last year, but this year its just never been like this before and absolutely great.........

I've finally got 75% of the surface of my 3 barrels shaded with water hyacinth, water lettuce, and duckweed. IMHO - you have done what needs to be done for clear water and only need to wait for the "algae bloom" to die off from starvation (sounds good, but I know it is difficult!) A bacteria additive also helps as it boosts the level of bacteria in your pond - I use it on a regular basis as it also eats up the mulm (sludge) and dead plant material in the bottom of my pond - my pond goes clear within 3 days of firing up my 45 gal bio filter with no surface coverage yet (open water) Gale :~) |
Patience, Patience, Patience. That is the one sure ingredient in any system
that works, and it sounds like you have the rest of the system in place. -- RichToyBox http://www.geocities.com/richtoybox/pondintro.html "Elaine T" wrote in message m...

LOL! Is EcoFix the kind of bacteria you're talking about? I picked some up a while ago by mistake thinking it was nitrifying bacteria. If that's the stuff, I'll go add some. -- Elaine T __ http://eethomp.com/fish.html '__ rec.aquaria.* FAQ http://faq.thekrib.com |
I'd add time to your mixture of solutions. Time and patience. Lots of patience ;-) kathy www.blogfromthebog.com |

ak!
I didn't mean to post it twice but google, the internet or my computer have been a bit odd today...! k |
here's my mixture of solutions:
uv sterilizer barley straw lots of aquatic plants i think that plants and straw alone should control the algae. a uv sterlizer is harmless to plants and fish. chemicals are the wrong route, unless it's barley extract, but whatever works for you. |
Is EcoFix the kind of bacteria you're talking about? I picked some up a while ago by mistake thinking it was nitrifying bacteria. If that's the stuff, I'll go add some. Hi Elaine - I don't know "EcoFix" - if it is a bacteria additive , it should help. I use "Bacta Pur" myself. The bottle will tell you if it is bacteria. I don't use floctulants (sp?) or anything else in my pond - only the bacteria additive Gale :~) |

Stop any fertilizer and do water changes of 10% every 5-7 days, no more, no less. More can cause green water in some places, less just isn't enough. There will be enough traces elements in the fresh water to feed the plants. Anything in baskets/pots with soil, feed with rose stakes buried into their soil. Some fertilizer mixtures add more stuff than what it is listed. Especially if using something not listed for aquatic use. ~ jan See my ponds and filter design: www.jjspond.us ~Keep 'em Wet!~ Tri-Cities WA Zone 7a To e-mail see website |

Don't I need the plants to be living on nutrients in the water? Fertilizers, especially phosphate bind with the soil, especially clays, so they don't leach. Many of us feed our plants thus, and have no green water. ~ jan ~Power to the Porg, Flow On!~ |
