The piictures speak for themselves. Last year I had a cover put on my pool. When I looked at it in August this is what I found . The pool was green with algae. Their advertising states "no green pools". The cost for cleaning my pool and refilling with water was $520.00 Tom, the owner, sent me a check for $125.00 I He says I am now blackmailing him for the additional $395.00 that it cost to clean my pool. Buyer beware.
