Chalky water with protein film - bacteria issue?
I originally thought this was related to the GH Booster I coincidentally added just before the chalky/milky appearance issue began, but I've since virtually drained the tank and replaced the tapwater with DI remineralized with Salty Shrimp GH/KH+. Despite that, I can see the chalkiness and protein film reappearing, leading me to believe it's a bacteria issue, rather than chemical.
It's a rock, sand, and moss 7.5g open top tank with two snails, awaiting shrimp. NO2 reading is zero.
What's the best way to deal with this?
Getting back to the hobby and up to speed.
