Had to respray 3 or 4 times on the calcium line to get it all off but it does remove calcium, etc buildup

I live in the country and we have very hard well water. I noticed that there was a lime deposit developing around the pool. I used this product along with a pumice block and a white eraser sponge. It took the lime deposit away. Unfortunately the white line is back but that is not the fault of the product. Mineral Content of the water in this area makes the product a must have for pools.

I was a little skeptical when I buought this Bio-Dex #300 as we tried some chemicals that didn’t work at all, and I couldn’t find many online reviews of the product. We have our pool for more than 15 years, but our pool tile is not that dirty and we haven’t cleaned it from before Covid started. Before that we used the scrubbing foam bars, but then we needed to wash the filters to take out the silicate of the bars. I bought 2 bottles from Walmart and with only 1 bottle the result is magnificent. If you use this product every year or even every other year the cleaning process will be very easy you’ll need just 1 bottle of Bio-Dex #300, a plastic brush and a pair of strong hands/arms. Thank you Bio-Dex #300 for making my pool looking new again and my family happy
