I just signed a contract for my new pool. I'm going old school with the rainbow 320 inline feeder. I've been reading alot about trichlor (what i plan on using). The main drawback is it raises your cya over time.
My dumb newbie question is this: Why don't they make some other kind of 3 inch tablet with very little or no cya in it that you could switch to once your cya level gets too high? I know you can switch to bleach, but it would be much easier to just pop in a "cya free" tablet once your cya got too high.
Or if that's not possible, is there another chemical that lowers cya?
Please educate me.
