Well actually yes they did ask for help. Turning their pool from the brown/yellow metal stained 20,000 gallon sink hole to what now, after the ascorbic acid and algae control treatments over a period of three weeks of twice daily treatments by me, looks like a brand new 16 year old gunite pool.

Now they interviewed one pool person and because this is not my trade just my hobby they are convinced he has all the answers. To quote, "Who should know more you or he that does this every day for a living?"
