Bio-Dex Protect-All Supreme, 1 gal. PA04

my husband and I decided to chemically clean our pool so we pump out all the water and chemically cleaned it with this product and a couple of other products of the same brand and it did work very well but maintaining the clean is kind of hard afterwards using this for maintenance so it doesn’t get stained as it did last time

Bough, At my home 7 years ago. Came with pool. I live in Phoenix, Az. Has terrible water. Already had ring around pool, calcium. After adding one quart of Bio-Dex to pool, ring is pretty much gone. Love it.

Working well for me 4oz a week keeping tile nice

Update 27 Jan 2022........no effect at all.Ok so it's been in my pool just over a week now, 20k gal pool so I put in about 1.5 qrts, it calls for 1 qt.All chems are fine across the board, left pump running for 2 days straight and rhen the scheduled times, still about 10hrs per day.The white line that was there in the beginning (very light) is still there today so I see zero difference.As of now I rate this low, if this stuff removes the line then I will come back and update this to a higjer rating.

Only good in the pool…not good cleaning the high water mark
