I'll second that. It's a very useful little book and not expensive. It's my
most battered and used-looking book. Get it from the Aquatic Gardener's

I have MT snails and they don't leave anything like this around. Sounds
like an aquatic mushroom. Is there such thing? Perhaps you should take it
out, keeping it whole and put it in a separate container with tank water.
Are you near a university that could be interested in examining it?

What I do is first float the bag until the temperature is the same. Then I
open the bag and take pH readings. If they are different I use my fish-only
measuring cup to take out a cup of water (if there is a lot of water in the
bag) and put that down the drain. Then I add a cup of tank water. Wait 10
min. Take pH. continue.... What's really frustrating is when the store puts
a pH buffer in their water so that you have to take out practically all the
bag water before the pH starts to change.
