Knight Posted December 8, 2006 Report Share Posted December 8, 2006 Hi everyone, We have a 100L tank, that's been going for 6 months, after the initial set up and cycling all levels have pretty much been at zero, although lately we've been a bit slack on checking the levels :oops: , but we do a 25 - 50% water change weekly. It has 5 guppy's, 3 platy's and 2 BN's in it, plus about 10 baby platy's. We did a 50% water change today, didn't do anything different, everything was looking fine, went to work, came home and the water's cloudy! We then did some tests, Nitrate is 5, Nitrite 0, pH 7 and Ammonia 0.5 (after the 50% water change!). We have a bio ball (which we changed last week) and ceramic noodles in an Aqua Clear HOB. All the fish have been in there for atleast 2 months now and they don't seem to be affected by it. What could this cloudyness be, and how can we fix it? We also have bog wood in the tank (again, it has been in there pretty much since we set up the tank) if that could cause anything? :-? Also we have 4 other tanks that we also did a water change with today, and they are all fine. Is that enough info? :oops: :lol: Thanks for any help on this Quote Link to comment Share on other sites More sharing options...
suphew Posted December 8, 2006 Report Share Posted December 8, 2006 In a cycled tank you shouldn't be able to measure any ammonia, I suspected that whatever you did to the bioballs has disturbed the filtration and what your seeing is a bactreial bloom. I would suggest that you just keep an eye on the ammonia and make sure it doesn't get too high (change some water if it does) and otherwise just leave it and let it cycle again.

Knight Posted December 8, 2006 Author Report Share Posted December 8, 2006 OK, cool thankyou. The water doesn't seem as cloudy today but will do another water change to try to get the ammonia level down to 0 again. Good news is our fish don't seem to be affected by it at all. I was so worried it was going to get worse! Thank you again for the advise Quote Link to comment Share on other sites More sharing options...
IOU1 Posted December 8, 2006 Report Share Posted December 8, 2006 Also be sure you oren't overfeeding your fish They should be able to eat all the food in a couple of minutes. 'A slightly hungry fish is a healthy fish' Don't starve them though..... :-? Quote Link to comment Share on other sites More sharing options...
