Just curious..
Have seen allot of posts about the dangers of a deep sand bed, but has anyone had their tank go sour by one?
I know the baddies can grow in the anaerobic environment, that is a fact.
Just like a poorly maintained canister that has the power off for a time, read as little as an hour.
But what I would like, is any first hand, it happened to my tank occurrences of your tank being adversely effected by the escape of methane or hydrogen sulfide.
