Had a friend give us their pool "left overs" extra pumps, tubing and such... plus a couple of bottles of chemicals:

* Leslie's Ultra Bright (from what I've read I probably don't need this one either)
* Aqua Chem Filter Cleaner (bottle doesn't list ingredients, this is what I could find online: )
Dipropylene glycol monomethyl ether 6%
Sodium Hydroxide 8%
nonylphenol ethoxylated phosphate ether 4%
Benzensulfonic acid, dodecyl(sulfophenoxy), diammonium salt (DDBSA) %
would love to know if this filter cleaner is safe to use on my cartridge filters (right now I just have the Intex ones)

Thanks!!
