My husband and I have decided to resurrect our old cheapo above ground pool for another year. We are retired now and just want it to cool off in, but the costs of chemicals are so high and we always goof up the pool.

It's a 15" by 4" older one of those flexible wall ones. We bought a used Heyward DE filter instead of the little one that came with it. We've had this whole setup about 15 years.

I'm very interested in figuring out this BBB system. What we did other years was loads of work and we never seemed to keep up with it. And of course the winter cover shifted and it filled with leaves. Really nasty sludge mess, will be quite a project. Any advice, and no we can't afford a new one.
