Re: Problems with my tank fish dieing

Nasty!  I knew there was a reason we don't keep souped-up substrates in
our hatchery tanks.  

I have no idea of why this happened without some sort of test results. 
Was there a high amount of nitrate or ammonia when you pulled up the
substrate?  Usually you can smell H2S before it gets to the black root
