So as I'm still learning and finding my way around, I have a quick question about chlorine stabilizer. I think my tabs have stabilizer in them, but I saw a 4lb bucket on sale for about $10 so I bought two. I'm trying to read more about it, but is this a chemical that I'll need a constant supply of? (the store has more-- should I get a bunch?) or is this more of a one-time add and it stays in the water?

Still waiting on my K2006.
