FC 12 (really same as this morning, three of us agreed just now it's closer to 12 than 10)
pH 7.8

Water clear, again not as much "mist" on the bottom while swishing the water around, I can live with it. Filter barely had anything on it. Put in more bleach just now.

Question about surface skimmer......it has a partial black ring where the water hits/sits on the top edge. Rubs off but "greasy/smeared", I cleaned it off with 100% bleach on a paper towel. Algae starting? Mildew?
It was there this morning too but I forget to post about it. Water still pretty cold but I'm getting in after supper to stir up the water some more.

Will I need this new bottle of metal control stuff I bought?
