I used the baking soda method recommended on the Reefkeeping magazine website. It seemed to work like a charm yesterday when I did it. But this morning I wake up and everything in the tank is coated white. All the parameters in the tank check fine: Ammonia - 0 Alk - 2.8 PH - 8.0 Nit - 0. Should I worry or is this sometimes normal with this method? The snails, crab, and the only fish (lawnmower blenny) are doing fine.
