2 years ago, I to fell into the pool store line that I had high phosphates and that was the reason for my algae problem. So I bought and used a couple hundred dollars of No-Phos. Other than sucking money from my wallet, I never saw any other effect.

I got my borate test strips, my borates are at 80. Probably because I had added 2 boxes of Borax right after I had opened the pool and my ph was low. I shouldn't have. I didn't know about aerating at that point. I didn't think much of that would be left after all the refilling I did during vacuuming to waste.
