Good morning. I am very glad to have found this site!

I have a 15 ft round above ground Intex pool (48 inches high). There are little stringy things all in it. I shocked it a few days ago, and have a flippen frog that was recommended to me by my local pool store. Also, I don't think the pool pump is very good. I have had this pool up for almost 3 weeks, and maybe the filter needs to be changed. I am afraid I am confused about what products to buy and how and when to test. I would like to know how to fix and maintain my pool.

Thank you kindly.
