Pool Readings: FC = 5 pH = 7.4 TA = 70 (Just added baking soda to bring it up to 90) CH = 250 CYA = 50 Background: Had pool replastered on June 2007. 10/2007 - 4/2008, covered pool and didn't attend to it over that time. April of 2008, cleaned the pool and kept it clean, except for 1 or 2...

I have a skimmer with two holes in the bottom. One I know is the regular suction to the filter, but what is the other one for. The problem is that a rock dropped into that hole. I can see the rock and can partially get some screwdrivers on each side but can't get it out. So actually I have two...

Refer to http://www.troublefreepool.com/diary-of-a-swamp-t15087.html for the whole grueling tale but more specifically I brushed my pool this morning and noticed a lot of small white particles about the size of cal-hypo but I haven't added any in several days and I don't think it is plaster...

Is there a formula somewhere that indicates what the increase in calcium is per amount of cal-hypo and increase in CYA per amount of trichlor 1lb of 73% cal-hypo for 21000 gallons of water = x calcium increase 1lb of trichlor for 21000 gallons of water = x CYA increase

I hope my topic is not improper since it is more of a diary of my steps of going from swamp to pool as opposed to a question. I was wanting a synopsis of what I did to correct my problem for posterity. However, I would love any comments if it seems I've gone astray or on the right path...

I'm replacing my filter with a side mount sand filter using a 7 position multiport valve. My current system had a DE filter with a backwash tank and between the filter and tank there is a check valve. I have since removed the tank and backwash to the sewer system but since I'm replacing these...

Sorry to be such a pest but I want to do things right as I am replacing the filter and pump. I've posted a few questions concerning filter size but the response I got was based on the pump which I've decided to also replace so I want to make sure the pump is the right size. Originally, the pump...

I'm converting my DE filter to sand and thinking about a Hayward Pro-series side mount and was getting conflicting sizes, so I wanted to get your opinions as to the right size. My pool size is about 21k gallons with a 1.5 hp pump, 2" plumbing in and 1 1/2" out. I currently have a 48 sqft DE...

I have a question about my system. I'm having a couple of leaking issues and feel now is the time to replace the filter from DE to sand. Anyhow, I've noticed that I have two inch piping from the spa and pool to the pump (1.5hp motor). Two inch piping out of the pump to a two way valve. One side...

I'm opening my pool and I would hope someone could help me with the best sequence to do it in. My measurements from the TF-100 kit are: FC=CC=TC==> Assuming zero since very green and no chlorine added for several months pH > 8.2 TA = 40 CH = 330 CYA < 20 Temp = 75 I'm not sure about CYA but I...
