I never had a pool before my current one and was relying 100% on pool cleaning service. But after seeing pool guy spend 3 minutes at the pool and charging me $80 per month, I found TFP and decided to take care of the pool my self. Asked a a couple stupid questions so far and answer helped alot since it was regarding how to operate filter! So far keeping up with Cl and using filter regularly seems to me more than adequate enought to keep the pool nice and clean! Only thing is that I have no clue how to turn on underwater light or turn on the waterfall. I tried to turn on all buttons I can locate outside but no luck. My question is where do pool builders usually put switches for them? Sorry again for silly question but thanks in advance for any reply!
