Chemical confusion!

[NEWBIE POOLOWNER]

Ok - I remember our above ground pool from childhood - we had a DE filter and all the chemicals I remember my Dad adding were powered chlorine and possibly baking soda, now I have about 6 different kinds of stuff to change the water levels and am totally confused!!! THE PROBLEM is that I have been testing my pool since early June and within a few weeks of crazy results finally got it stabilized after using a stabilizer/conditioner. Everything was fine until the water temp remained at 90 degrees F for weeks and then got very low or no chlorine lvls, pH too high or low, alkalinity too high or low (I assume connected to pH) Cyanuric acid level remained good. Then got cloudy water, now green tint, added algaecide and it's foamy and the water feels slippery. I have been adding products from big box store. Is it time to got to pool store? I have a 15X48 vinyl pool with metal framing and orig cartridge filter. HELP and Thanks!!!

Shock the pool by adding chlorinating liquid or 6% unscented bleach. The increase in chlorine demand and the cloudiness was algae starting to grow. Your Free Chlorine (FC) level got too low relative to your Cyanuric Acid (CYA) level and allowed algae to grow.
