Just wanted to let you know your website is wonderful! I had started to present a problem to your msg board earlier, but in the middle of posting it, decided to go out to my igp one more time to see what may be causing the water pressure issue, and noticed one of the "screws" on the pump filter basket wasn't tight. Once I tightened it, the water pressure came back and I am all smiles again! I am a 61 yr old grammy trying to maintain my one year old pool. I don't understand all the proper pool terminology but am slowly learning. Heck, I dont even understand the correlation between PH and Alkalinity, but i just learned Alkalinity is adjusted first, then check the PH! I think there are probably cheaper ways to treat my pool water, but until I learn what is what, I havent even attempted to sway from my pool people yet. They have been a big help to me so far. Again, thanks for this website and keep up the good work!
