I bought my house last August I have been TFP since day one. Last year I did great and over the winter I really studied and now understand chemistry, know my pool, confident in my testing etc.
Over the winter I had all of my equipment rebuilt, cleaned, new sand in the filter everything looked at and everything is working flawlessly. I ordered a new light ring because mine had a crust of something on it. Well the pool guy just hasn't got here to put it on. Sunday my daughter and I scrubbed on it and we got so much off. It was quite impressive but my problem is, I have been fighting a cloudy pool for a couple of weeks. It looks terrific but at night it is "off" I always run DE in my filter but lately I have been having to backwash every day or other day. Pressure is rising so I know it's working fine. Last year I went 6-8 weeks between backwashes. Before this started I was going around 3 weeks between backwashes.
I know my chemistry is fine and I have passed the OCLT four times in the past two weeks. Chlorine loss is normal. So I wondering if having proper chemistry is breaking down this calcium buildup in the equipment. I am finding a lot of grit in the robot filters and have started noticing grit on my steps. Last year I tried scrubbing this ring and nothing would budge on it. I defiantly am seeing less of the calcium on the ring since Sunday. We wore our brushes out and nothing else was coming off for us so we stopped. Last night I touched the ring and a bunch just rubbed off. As soon as I started noticing the cloudiness at night I started scrubbing every single thing in my pool with a toothbrush multiple times so I know algae is not causing the cloudiness.
So my thinking is that this calcium coming off in the equipment and this is causing the cloudiness at night. Is this a reasonable explanation?
My test results from Monday
CYA 30 I am being generous here. It doesn't hit the 30 mark. I am trying to get this up but with all the back washing I am struggling.
All I have used in my pool this year is bleach and CYA. Everything else has been stable since opening on March 23.
