To make a long story short, I am a shift worker at a local Refinery. It is hard for me to give my pool the care it really needs during the summer months so I have hired a pool guy.(big mistake) Anyway, I have a 20,000 gal in ground plaster pool with a hayward D.E. filter and I believe a 1.5 H.P. pump. In Houston so it is Hot almost year round. My Problem is every week the pool guy gives me my report about what he had to do to the pool. It always is the typical cleaning, backflush, skimmer, etc. etc. What I have a question about is the chemicals or lack there of. He has not shocked it yet this summer. He only adds 4 o.z. of No more Problems and puts in 4 of the 3' pucks. I told hem we had 30 people in our pool this past weekend and I knew it needed to be shocked. He checked and said no it did not and that the No more problems acts as kind of a shock. I have to say my pool is crystal clear. I have never had a problem with cloudyness or green water. Only after the hurricane last year but it cleared up soon after. Should he be shocking like every 14 days or at the very least after a heavy load of 30 people? I check my water every other day or so and I have been getting like a 7.2 P.h. and Chlorine is usually around 1 or so . He says the chlorine is way high, but On my tester it comes out the a 1 or 1.5 at most. Should I be worried about this guy or what? I am considering making time for my pool and going BBB.
