Wow what a wealth of information you guys have here!
I just bought a short sale house in Central Fl with a 12.5k inground pool. The previous owners didn't do much to keep up the pool, other than add chlorine (which was poured straight down the skimmer ).
There was a layer of green slime/algea on the bottom of the pool which came up easily with a quick brush. I ran the pump most of the day and bachwashed it afterwards. It had a couple minutes of nasty brown water that came out. Took a sample of water to the PS and said the FC was around 15ppm with the CC at 0ppm. They said bring a sample back in a week to see where the FC is and to go from there (this Thursday will be a week).
The filter looks to be a Pentair, the label was painted over so I can't tell the model and measurements put it somewhere around a TR-50 and 60. I'm sure the last owners never changed the sand and they had the house for 12 years so I plan on changing it. The only problem is there is about a 75lbs difference between the two possible filter sizes. Although looking more into the specs on the filters it has the level of sand being 9 5/8" from the top for the 50 and 10 1/4" for the 60.
If I were fill it to about 10" from the top, would that suffice?
Also the pump needs replacing. It's old, cracked/leaking and louder than a stuck pig! The serial and model numbers are faded away so i have no idea what size it is.
From the reading I've been doing it sounds that a 3/4hp pump would be just fine.
There are no valves on the plumbing. The main drain is hooked into the skimmer and I have placed a skimmer diverter in so I can get better flow to clean up the water.
Any recommendations on any 2 speed pumps?
The water clarity has come a long way! Not sparkling yet but should be soon.
I have a TF-100 kit on it's way.
Any input would be great.
