It's been a while since I browsed these forums (long enough ago that a new user _could_ actually browse them) but I have returned looking for information about polyquat. I believe the info I remember reading was that all brands of polyquat (in the US) was the identical except for the concentration, and that 60% was nearly always the most economical. What I don't remember is whether there was any advice for dosage other than whatever I find on the bottle?

I don't plan on regular use, but I am using a stain treatment (Jack's Magic Iron/Cobalt) that requires no more that 1ppm chlorine for 48 hours (and no super chlorination for 7 days) so it seemed some algae inhibiter might be prudent.

Any advice?

Thanks
