What a waste of my time - we have a small above ground pool that we have had problems with lately - seems like the more we try to fix it the worse it gets and I called to see about them testing our water and getting "professional" advice. Greg was very nice on the phone when I called but evidently was off as soon as we got there and said some other kid that was there would help us and Greg promptly left. I did not check his name tag but the kid asked what type of pool we had and how big it was and then immediately said to follow these instructions on the sheet he handed us and said we had two options treat it like this (i.e. sheet) or drain it and start over. THEN he tested our water and with the results promptly said the same thing, over and over - I told him we have to put chems in everyday and I check levels everyday and we got some algae but were getting it clean but now since it rained it's gotten worse. He just looked at my husband and regurgitated exactly what he had already said 4 times by now. We even mentioned that we were planning on getting a salt filter and he was like a robot playing the same track over and over. I wanted to talk to a professional and get some real advice I would probably have been persuaded to purchase products from them but I won't even bother to go back in and have them test our water again because we clearly do better looking up You Tube videos - they are over priced anyway.
