First off let me say that I'm ordering my test kit today. The numbers I'm posting are from Leslie's 2 days ago. I know that they will have changed since then but my main concern at this very moment is calcium hardness. Today I'm planning on taking a sample to another pool store to compare their results of the calcium hardness test (partly for fun - it's fun to see the difference, and partly because if it's in the same range of Leslie's, then I know I really do need to work on it).
You can see why I'm wanting to take care of calcium hardness right now. My other problem is we keep noticing a slight algae problem, but I'm sure that's just from not shocking long enough. I'll post questions on that soon. Leslie's recommends almost 18 1/2 pounds of Hardness Plus. I saw in Pool School Hardness Plus was one of the things listed to use...but I just wanted to make sure that is okay to purchase and there's not something a little simpler to purchase to use. I see on poolcalculator.com it says to use either calcium chloride or calcium chloride dihydrate...I don't know what those are or where to find them (help?).
Another sidenote: We resurfaced our pool almost exactly 12 months ago now. I'm surprised that our CH has dropped like it has. A few weeks ago I tested my water at Leslie's and got a reading that was of no concern (don't remember...I'm sure I have the results somewhere but can't access right now). Is it possible the lady just did the test wrong? Should I wait until I get my test kit or do it because of what can happen if you have low CH? Just concerned about our new pool finish.
Sorry so long. Thanks for the help!
