Liner Pool Care

The pH is always on the low side......which I thought was due to adding 2 stabilized chlorine tablets each week. Most of the time I need to add soda ash to raise the pH.

That is the problem I am having, Chlorine won't stay in the pool. Each week I go back the levels are low. Last year i did not have this problem, although it wasn't nearly as hot as it is now this time last year.

Which, in turn has also raised the TA.

Last year the CYA levels were probably not as high so the chlorine was more effective at keeping nascent algae at bay.
With the higher CYA levels now the chlorine is being consumed fighting off algae that is getting a "foot in the door" because there is actually less 'active' chlorine in the water amd more held 'in reserve' by the higher CYA levels if you are keeping the free chlorine at the same level that you did last year. The higher temps cause the algae to grow faster adding to the problem.

Yah i need to drain the pool some, maybe do it a few times. Did you take a look at those pictures? Can you see those gray/blackish spots at the bottom?

See that ladder and the bags next to it? It's actually bricks I think in there to keep the ladder in place.....HA! I didn't do it the home owner did, any weird effects with bricks being in the water? I know it cant be good.
