I checked that L palce online and I didn't see any liquid.
My closest pool store has 4 big (or whatever size oz.)gallons for 14$ or so 12%..still like to find cheaper.
Does the L store [or maybe it's just a brand name]
'Chlor- Brite' good or does it have CYA too.It says it's PH nuetral and can that go in a inline feeder?????.I would use it just to keep a little chlorine going in feeder but quit buying the borax,so it be worth it if it cost a little more.
