I was thinking of doing another water change today is this a good idea?? he still isn''t doing well haning out at the botton not really moving and upright more then straight and Dirty (my powder blue gourami) is also acting sick spending alot of time (way more then usall) on the top of the tank. and when he dose swim around it seems to be in circles instead of straight and he is getting a very dark blue line down the front of his boby (this has been happening for about a week now but becuse he is a blue fish i didn't know if it was normal or not) and his body seems to have a bend to it?? am I over reacting ??
Don't touch the filter. It is very difficult giving advice when we don't have the actual numbers. If you have fish dying within the first two weeks, I think most would agree with me it is probably ammonia or nitrite, not nitrate. And anyway, to actually kill fish, nitrates would have to be extremely high which is just not probable in a tank this new. And further, the solution to high nitrates is always do a partial water change. Not that I'm suggesting this here, yet...just pointing out the correct solution for high nitrates.
Cycle has worked for me and others, similar to Stability. It depends upon what may be causing the fish losses. If it is ammonia or nitrite poisioning, Stability will help; I know of nothing else for this except a partial water change--and on this issue, yes, I would do one each day. As you have cycle, do a 50% change, use a good conditioner of course, and add Cycle. None of this can hurt.
If the deaths are due to something other than the above, I am at a loss to offer anything. I'm not good at diseases, others here are; hopefully they will be following this thread and jump in if they recognize something.
Relatively unimportant until we resolve the other, but weekly liquid fertilization is always beneficial in a planted tank, even with enriched substrate. It all has to balance though, so very little once a week may be enough. Wait until things settle down before putting more stuff in the tank. And if you only have one sword plant in the tank with a Plant-Gro stick beside its roots, that may do it. Monitor the plant. Expect some of the existing leaves to die, that is natural, and new leaves will grow; won't go into the "why" now. If the new leaves that will be nice and green begin turning yellow later, liquid Flourish Comprehensive will remedy that.
