Never owned a pool before but over the last month I have learned that the supposed experts at the pool store do not know any more than me. The previous owner used trichlor tablets and calcium hypo for shock. I am using liquid chlorine.
I am losing 3ppm chlorine daily and have significant white scale around the edge of the pool.
Here is my plan. Please correct me if I am screwing something up.
Drain 10k gallons then refill two times which should be about 60% water change. Hopefully this will get my CYA and CH back in order and make everything else easier. When I drain the water, will scrubbing with muriatic take off the white scale?
After the water change, I will test again to see what my TA is the start lowering that with the muriatic/aerate technique. Hopefully that will reduce my chlorine input.
Re. The Liquidator- From reading all of the posts about installation, I picked up that I would not need the check-valves with a below ground pool. With my pool, without the valves installed, the Liquidator allowed a bunch of air into the system when the pump shut off. After I put them in, problem solved. Question. When adjusting the flow rate, are we supposed to look at the ball in the meter, or the water level in the meter? I thought the ball would be floating in top but it isn't.
