|puopg||You did do a big WC after you moved the substrate right?|

A few bubbles wiped out that many? I would have thought it could only affect those directly exposed or close to it. Sorry about the loss.
That is a good argument for stocking a tank with MTS though.

|InannaMoon||Thanks, Addict. I don't think it would have been different with fine gravel though. It's our own fault for not stirring things up too regularly and letting it all build up. And substrate was probably a bit too deep as well. Trying to at least take comfort in that I get to choose a few new fish.|

So I was inspired by an article by Takashi Amano about using lighter substrate in the foreground and this weekend I pushed all my dark stuff and soil to the back of the tank, replacing the foreground with lighter gravel. Lo and behold, a few nasty bubbles and I've lost all my kribs and a neon.
Guess this is the anaerobic pockets people have mentioned. Never though it could be quite so bad but really awful situation. What did seem to help, besides the quick and frequent water changes was putting an airstone in to bubble away. It could have been a lot worse but guess I wanted to leave this as a word of warning for people.
