We have 7 damsels, 1 feather duster, live rock, 2 peppermint shrimp, 2 skunk shrimp, 5 turbo snails, 1 starfish, a couple nudie branches that we don't see to often and 1 big sabea anemonie. The 8.8 is what showed up tonight. other wise it tested perfected. And could this be why we have been getting ick on our fish so often within the past 2 weeks. Never had a problem before this. Everything was going perfect till now. I have forgotten yes we have been treating the tank with ick attack.
