Just got back home and did another test. Here are the parms Ph 8.0-8.2, N03 0, N02 0.05, Alk 1.7-2.8, Ca2 480. And from test before that is about what it was before everthing closed up and nerite snails stopped. fish, crabs, and nassatius snails seem to be doing fine. Havnt done a dip but picked them up and didn't see anything on them. Have to go get water tomorrow so i'll dip'm then.
