Odor in Pool after Algae Treatment

[TerGerKub]

Thanks. In regards to using bleach - are you referring to shocking or maintaining chlorine levels? I have also began to drain / dilute with fresh water to work the CYA down to a more resonable level. Thanks for your help.

That's sort of a 'distinction without a difference' - the pool biz likes to treat them separately, so they can sell you BOTH "chlorinator" and "shock", often with the same ingredient in each.

We use "shocking" here to refer to raising the chlorine levels higher than 'normal'.

Think of "shock" as a verb, an action, not "stuff". That way you'll always know what you are doing.
I shock almost exclusively with Liquid Chlorine (Same as bleach only twice as concentrate). I currently don't have ANY Cal-Hypo or Di-chlor in the house, and only a tiny bit of 1" Tri-chlor tabs.

I went into my favorite pool store yesterday (the one where they actually do NOT sell calcium boosters to vinyl pool owners) and asked for CYA. Kid didn't know what I wanted. "Cyanuric Acid. You know, Stabilizer". "What do you need it for?" he asked. I said "Are you kidding me? I know EXACTLY what I need it for." Then he went into a song'n'dance about how people use too much (true) and how I shouldn't buy more than one lb. I said "Look, I know how to use this stuff and even how to run a high chlorine pool." Pretty funny.
