Hi everyone, this is my first post. I would appreciate it if some one can help me. I've just build a brand new 19000 gallon salt pool and spa from ground up. Finished on September 2015. Quad DE Filter. For couple of months it was ok, but in the last 3 months it has been It has been crazy for the last three months.I've been getting large amount of calcium buildup on the glass tiles around the pool. It's like salty flaky and it builds up like a Christmas tree starting from the grout between the tiles. If you leave it on long enough I will get hard and stick to the class also, but you can flick it off with your finger when fresh. We live in Granada Hills California. It's very windy here. For 6 months out of the year the wind blows from the north and the pool water constantly moves up and down on the tiles. I also have a bubble cover on it now. when I brush and clean the tiles it will just take four days for that Christmas tree crust calcium buildup to form again. The glass tiles I can clean but the grout is hard because it's more porous. Gray color grout turning white. Please see attached photos. Please help I've been brushing like every week with calcium cleaning soap.
On a normal pool how often do you need to add the muriatic acid?
Do you add it to enough to keep it in the range 7.2 - 7.8?
Does the grout have anything to do with the calcium, or the wind or other things?
Dose the pump speed matter?
Can it be the wrong grout?
What am I missing here?
