Snails will feed on the remains from your fish.
wow! I totally misread that and thought you said the snails would feed on the remains OF my fish - LOL
I don't have any plans to alter my water chemistry now - frankly I was concerned about trying because it it doesn't stay stable, all manner of problems would come my way. I feel much better, and more comfortable, about the tank now that I better understand some of the chemistry involved. I'm reading as much as I can, and understanding more and more - thank you everyone for all your help!
I have let the small broken pieces of cuttlebone sink for the snails to find, and I will keep feeding the veggie/calcium sticks. Last time I fed the sticks, the ones that the fish didn't eat were swarmed by groups of snails - a rewarding sight!
