as many of you guys that visit this forum a lot remember all my questions in my battle with a Black Algie nightmare infestation that has only worstened with the rise of water temp.... I throw in the towel and decide to drain and acid wash, I have researched the safety and everything else, I do not have a hydro valve, and the water table now ( low ) is not really a concern....what little secrets am I missing ?? also I plan to fix some of the coping while its drained. What kind of mortar would I use to secure 2 sections of coping ? as for the cracks under and between the coping what would I use there ??....what about expansion and contraction the coping backs up to a concrete walkway ( pool deck ) about 3 foot back from the pool I read the other thread, but what about tile mortar for laying ceramic tiles, I did not think that would be for a constant wet type application, what do the pro's use for setting pool coping ? thanks

I was wondering. I have a 2HP pentair whisperflo pump for my pool and my pool guy tell me I can install an impeller to reduce the noise the pump gives off. It's really loud. Can anyone tell me what this means and if it's really possible or is he just trying to get more money from me. Thanks for any info. MG
