So my water is so clear in my Intex above ground pool with a vinyl, no porous liner, it looks drinkable. This was after battling mustard algae by super shocking it, then brushing and vacuuming to waste. I added a clarifier with phosphate remover and a Pool Rx copper ionizer. Water was absolutely perfect for 3 days (accept for mosquitos that my skimmer battled with constantly). Then black algae started to gather on the floor. Vacuumed again and added more shock. Added baking soda. The next day added more clarifier. Tested with HTH test strips, which read super high chlorine and high Ph. Took sample to Leslies whose tests were complete different results and they prescribed another $300 worth of chemicals including alkalinity up, more shock, an algae remover, an algae preventative and more salt. My pool runs 24/7. Always has. I am spending more in chemicals than the 17,000 gallon pool itself.
Please help!
