Hi. I am still having what seems to be an algae problem. We have been working on this and sinking money into chemicals for 3 weeks now. The 1st pool store we had our water tested said our alkalinity was low and to add 45 lbs and now our Alkalinity level is 240 and can't get it down and can't get our chlorine level up. We took another water sample to the pool place that installed our pool and said we had some kind of algae. Told us to do a vacuum on waste, heavy shock for 4 days, use Algacide and clarifier. We have done this but we still have a yellow tint on our deep end but the shallow end is fine. We are at our wits end! Can you help!????
