Hello all, I've been lurking at this site, and using the TFP methods on two of my pools, for years with very good results. A recent dust storm put quite a bit of fine dirt/silt into my current gunite pool, and I've run into some issues with water clarity, possible staining from iron, and water chemistry stability. So, it's time to register, and get some direct interaction on the water issues I'm running into. Cheers, JK
