JWoods Posted March 17, 2009 Report Share Posted March 17, 2009 Struggling a bit with high nitrate (ammonia and nitrite are zero, ph around 7.5) tanks are well filtered, Canisters with noodles, aqua clay, fine and coarse wool plus powerheads in some and biosponge filters in others. Know they usual things (less fish, ceramic rings, water changes, feeding less, more filtration etc.) but would be interested in hearing if there are any great products out there that actually works. Anyone with some good experiences? Cheers, JW Link to comment Share on other sites More sharing options...
dem0n Posted March 19, 2009 Report Share Posted March 19, 2009 a mate of mine played around with a home built denitrator which had bacteria you had to feed weekly with sulphur... it smelt bad & was way too slow to remove nitrates as fast as they were being created. as far as i know the only real ways are less fish & less food or a higher frequency of water changes. i let my 8' tank get up around 100+ppm of nitrates & it took 8 days of doing a 20% water change every night to get them back to around 10ppm. now i do a 20% change every week (was doing 10% every week) to maintain a constant 10-20ppm of nitrates. in my african tank i'm really up against the 8ball... because most people suggest that with malawi mbunas you need a fairly crowded tank to lower individual aggression. but because of this, even with very light feeding, the nitrates rise very quickly! i feed just enough so the smallest guy doesnt starve to death... but still i have to change 30% of the water every week to maintain low nitrates (10-20ppm). damn i hate those nitrates! *shakes fist* Link to comment Share on other sites More sharing options...

roboat Posted March 22, 2009 Report Share Posted March 22, 2009 Seemed to work for me I made a diy canister with an oversized pump that was outside the window, because it was white/slightly clear algae grew inside it and seemed to keep nitrates low even after no water changes for 3 weeks.

jimbozed Posted March 23, 2009 Report Share Posted March 23, 2009 i have to say they do, i just checked the nitrates now and they are less than 10 i did a water change about 3 weeks ago and one maybee 5 weeks before that. i have to admit because of the sailfin the bottom is a mess of crap but all the fish are doin great. i was sceptical but bought 2 and am happy with the results. i have been real lazy of late and do usually do water changes more often.

Motorman Posted April 6, 2009 Report Share Posted April 6, 2009 You can also use Purigen I run it in FBF on my display tanks and I can keep the Nitrates down pretty low even when they are overstocked Plus U get the added bonus of crystal clear water Brad Link to comment Share on other sites More sharing options...
