Made an impulse buy without researching trying to understand pool chemistry. Its a coleman above ground vinyl pool, using the pump it came with so dont know much about its abilities. Starting to understand the concepts and why the level ranges are important. Just having issues with the details. I only knew pools took chlorine but now I have one I know how many different types there are and there are 2 levels testing for, not to mention all the other chemicals needed for balance. I fear I need a little hand holding and this forum seemed like a great community to go through this with.
