I've been lurking the forums here for a few weeks now and have been very impressed with both the knowledge of the members and the friendliness everyone has towards one another. Kudos! Not to mention, after seeing some before and after "swamp" pictures posted by various pool owners, I'm certainly a believer in the TFP community and methods!
So, here's my story...
I bought a new home last October and it came with a pool. It was certainly one of the selling points, but now I'm cramming as much information about pool maintenance that I can. The pool is currently only half full and was closed by the previous owner. After the bad winter we had here in Ohio, I must have lost some water to "heavy cover displacement". So, as I began to unearth the pool, I noticed that the skimmer box and return port were all caked with clear caulking. The skimmer wasn't even sealed very well between the inside and outside of the pool walls. When I attempted to tighten it, it had no bite left. I ended up replacing both parts with all new rubber gaskets and fillings. I also hooked up the pump and filter to get the water moving (with hosed dipped in the pool since it's below the skim line) and get an initial test reading. There is little to no debris in the pool thankfully. Here are the test results (K-2006).
CYA 70 (previous owner used tablets)
So with the CYA being on the high side, is it safe to assume that CYA will be proportional when the new water is added? So for example, my pool is currently at half capacity and reading 70 CYA. When it is filled on Friday, will this dilute the CYA proportionally to 35? I plan to test again after it is filled and circulated for a bit, but I was simply curious.
Also, can/should I do anything at the moment to begin the SLAM process with the 10.5k gallons already in the pool? I think the CYA may limit my success, but I will ask the experts here. The water is currently slightly cloudy to mostly clear. I have 8 gallons of 12.5% bleach ready to go!
Let me know your thoughts and any other things I may have overlooked. I appreciate your time and assistance!
