Hey everybody, I'm new to the forum. I've been trying to fight a rather persistent algae growth recently using over the counter supplies and such, but it feels like a losing battle. I think the core reason is that my pool isn't getting enough chlorine circulation. I've got a chlorine circulator (a Rainbow Lifegard 300), for which I replaced the elbow check valve earlier, but the tests show me that my chlorine and pH levels are dangerously low. I feel like I've been shoveling in shock powder and chlorine tablets to no avail. The water is clear but I've got what looks like little clumps of yellowish algae still coming back even after pouring in around ten ounces of algaecide 60 and shocking it with ~4 pounds of 73% calcium hypochlorite.
I tested the pH and the chlorine levels with my Bioguard multitest today, along with a couple of the Leslie's strips. According to the tests, my pH is low and my chlorine levels are practically nonexistent.
