New to the pool maintainence part of swimming pool. I have shocked my pool with 2 different types of products,one was leslies powder plus and the other clorox extra blue for what I thought was a mustard algae outbreak. The clorox product cleaned the water up nicely but when the dust settled there was my problem again. I'm beginning to wonder about what my problem really may be,if not algae,maybe pollen??? When I first started using my sand filter it seemed fine and after a couple of weeks it doesn't seem to filter out the finer particulates now. Question: what does algae turn into when it's dead and how is it removed,same for pollen?? When I vacuum it turns into a watery dust cloud and in the morning there it all is again should I just exhaust? Do you have to "slam" all algae outbreaks or will algicides do the trick? Thanks for any help
