mitzy Posted March 26, 2008 Report Share Posted March 26, 2008 Well my partner had a 150 litre tank with live bearers , kribs , cory's and a couple of fighters. Last week noticed his problem was gone all were floating dead weird aye. since then fish have been dying at least one a day and water smells foul. he does do water changes, I am thinking as he has used sand and then rocks on top that food has got trapped and now there is a build up of bacteria. Water also has a green tinge to it. We dont have a test kit at this stage and tank has cycled. Fish are not diseased they appeared very healthy, The only ones dying are female guppies, guppy babies. Do you think its build up of bacteria? Quote Link to comment Share on other sites More sharing options...

Caryl Posted March 26, 2008 Report Share Posted March 26, 2008 I suspect dead spots of bacteria (possibly in the sand). Until you do something about that, just doing water changes won't be enough. If it smells foul, imagine what it must be like to have to live in it! Quote Link to comment Share on other sites More sharing options...
Guest Posted March 26, 2008 Report Share Posted March 26, 2008 If you take a water sample down to animates in melling they will do a water test for you. Quote Link to comment Share on other sites More sharing options...
mitzy Posted March 26, 2008 Author Report Share Posted March 26, 2008 what do you think he should do , daily gravel vacs? None of my tanks have this problem i have normal gravel. Quote Link to comment Share on other sites More sharing options...

Ianab Posted March 26, 2008 Report Share Posted March 26, 2008 Yes, do the water changes. Something is wrong with the water in the tank, some large partial water changes cant make things any worse. The only times I have problems in my tanks is if I get slack with the water changes and gravel vacs. Ian Quote Link to comment Share on other sites More sharing options...
Caper Posted March 27, 2008 Report Share Posted March 27, 2008 Someone correct me if I'm wrong, but with sand don't you have to "run" something (fingers for example) through it occassionally to release trapped gases. I can't think right now where I found it but if I remember I'll post the video I found on vacumming sand and part of the cleaning was running fingers through the sand.

curtur Posted March 28, 2008 Report Share Posted March 28, 2008 I think with sand as a substrate you do have to stir it up a bit from time to time as you can otherwise get pockets of anaerobic bacteria which are not a good thing to have in the tank.

vindy500 Posted March 28, 2008 Report Share Posted March 28, 2008 would kuhli loachs work to stir sand seeing as they like to burrow? Quote Link to comment Share on other sites More sharing options...
sharn Posted March 28, 2008 Report Share Posted March 28, 2008 Probably to some extent but they wont burrow through all the layers and might be reluctant to if the sand is already gross :lol: I always have a heap of malaysian trumpets in my sand tanks and they seem to do a pretty good job Quote Link to comment Share on other sites More sharing options...
mitzy Posted March 28, 2008 Author Report Share Posted March 28, 2008 He removed all the oraments and stuff and gave a good vacuumed so far no more dead and water smell has gone. so must of been a build up of bacteria under the plants, oraments etc. Quote Link to comment Share on other sites More sharing options...
