We are a retired couple and recently purchased a house that is 1,400 square feet of living area and 1,100 square feet area with a 14' X 28' lap pool. Before we could use it the first time we needed to replace the pool heater. since then we have gotten into it with much satisfaction. We are still in the learning curve regarding the chemicals and maintenance and when consulting with a supplier of pool chemicals (also a builder) I revealed that I use the pool cover when the pool is not in use to reduce evaporation and maintain pool temp. The supplier gave me a bottle of Natural Chemistry "Cover Free and suggested that I use it instead of keeping the pool cover on as much. After adding the chemicals needed to balance the chemistry and some clarifier, I added 4 oz. of the Cover Free. 4 hours later I found what looked like pieces of snot floating in the pool and the skimmer basket was loaded with it. I immediately shut the pump down but do not know where to go from here fearing that the pool filter may be clogged with the stuff or how it might be affecting my new pool heater. Any ideas???
