WillskE Posted October 9, 2011 Author Report Share Posted October 9, 2011 another thing that pop to my head is that i got two bottles off diy co2 going on in the 200L but i have a air pump going with the filter also so i still cant be sure..

Caryl Posted October 9, 2011 Report Share Posted October 9, 2011 More details would help. What else is in it? How long has it been going? What symptoms are showing on the fighter? Have you the right balance of CO2? Too much? Lack of oxygen? etc Any other fish behaving out of the norm? Quote Link to comment Share on other sites More sharing options...
amtiskaw Posted October 10, 2011 Report Share Posted October 10, 2011 Have you kept an eye on your pH since adding CO2? Quote Link to comment Share on other sites More sharing options...
WillskE Posted October 10, 2011 Author Report Share Posted October 10, 2011 just check the nitrite is at 0 and the nitrate is at 5ppm, the co2 is been set up for atleast 6months, i just found in the thick java moss cluster a dead rasbora and a female fighter from the condition i think they all died around the same time, they all been fine for atleast a month, had the mollies for about 3months and the fighters 1 month im just surprised to suddenly find 5 dead. before the male fighter die he was just on the bottom gone side ways leaning against some plants. edit: the ph's been stable at 6.8 for atleast a month also from 6 before i buffered up abit Quote Link to comment Share on other sites More sharing options...
WillskE Posted October 10, 2011 Author Report Share Posted October 10, 2011 after going to hff i think it might have been a sudden lack of oxygen? they said the plants at night take in oxygen so even with my air pump going 24/7 my co2 at night just over whelms it? thats the only possible diagnosis so far Quote Link to comment Share on other sites More sharing options...

the-obstacle Posted October 10, 2011 Report Share Posted October 10, 2011 how often are you changing water and how much? I'm assuming ammonia is at 0? Any recent (within the last 4 weeks) additions (plants or fish) to the tank? Quote Link to comment Share on other sites More sharing options...
WillskE Posted October 10, 2011 Author Report Share Posted October 10, 2011 i change water every week about 15-20% i just did one yesterday.. its like suddenly the whole tank is filled with death with fish dying randomly and fish being destroy cause of infections...
