Hi everyone. I recently purchased a bestway 16x10 42" deep pool. It completed filling yesterday afternoon. I immediately noticed the water appeared tinged green. I went ahead and shocked it. Waited a few hours, tested and appeared that the alkalinity was low. I added some powder to increase. I covered and let sit with filter running since yesterday morning to today. I checked this morning and water is still tinted green. I checked and the levels of the water look good. I'm at a loss. Also this pool came with a small cartridge filter. I have a sand filter but need some hose adapters before I can use it. Our neighbor thought this was due to pollen as his pool had the same issue and it should clear up within 24 hours. I had hopes by this morning it would be clear and nope. My kids are anxious to get it there! Please help!
