my poor tank

okay, okay I give, I went out yesterday and bought some things for my tank. Sadly I lost my prized red gourami after I did a 25% water change. I bought some Start Right with Allantoin, and added it last night, and I bought some Stress Zyme and put that in. I found out that te bio filter was infact cleaned and removed of all life. So my apologies to wataugachicken, and everyone else. I hope now to save the rest of my fish and once it stabilizes I will purchase my red gourami again. My thanks to everyone who helped me, and put up with me.
 
the chemicals you add will most likely not help the problem you face.

you will basically have to recycle your tank.

you will need to test daily ammonia, nitrites and nitrates. these will give you an idea of how toxic the tank may be.
the ammonia and nitrites should not get above .25 ppm to keep the levels low you will need to do daily water changes.
if the levels get higher than that you will continue to lose fish.

after the tank has cycled you may want to consider weekly water changes..if you can;t do that consider every other week.
the proble you can face by doing monthly tank maintenance is what is know as OTS(old tank syndrome) where the fish get use to high nitrate levels and sudden drops in the nitrates may cuase issues or death. by doing more frequent changes you reduce the nitrates and stave off OTS.
 
Umm thank you,star_rider, however my levels were all tested bi-weekly and were alway normal, that wasn't the problem. The problem was we boke the whole tank own, and cleaned everything, and I mean everything. So the levels are all at zero, meaning I have no bacteria in my bio filters, and they are not breaking down ammonia. So it would basically be like a brand new tank, never having fish in it.
 
My test strips happen to be one the best out there. And I have freshwater and high nitrite levels are not good for a tank. My bacteria level is fine we have a bio filter and never changed that. And that is where most of our bacteria is.


I did that once relying on my bio-wheel to keep the cycle going, and washed out my gravel. I just started up a new cycle by doing that because my gravel was loaded with bacteria and I'd just killed it off.
