I've been using the 12% shock, ie double strength bleach from leslies/lowes/home depot.
It's a pain to carry the liquids, are there any good powder alternatives?
power powder plus-- 65-70% Calcium Hypochlorite, no disclosure of other chems, no stabilizer ie cya includes
power powder pro -- ibid
chlor brite-- includes stabilizer, not good, right?
fresh & clear-- 38% Potassium Monopersulfate, "no chlorine", huh, is that good
genesis shock - no details provided trichlor shock"
chlor brite -- 99% dichloro-s-triazinetrione, which provides 56% available chlorine, the highest you will find for any dichlor powder,
includes stabilizer NB: reacts with other chlorines to release chlorine and may cause explosion or fire, oh that's real friendly
