Hi guys,
I am a new Home / Pool owner and have found TFP to be a great resource so far! I have experience in anylitical chemistry and chemical engineering, and as such I've found managing my pool to be somewhat entertaining and not overly daunting, but I am still a novice to pool chemistry and systems.
My pool is plaster, "L-shaped", includes a spa, and is approx 15,000 gallons, FW. The pool has two fixed speed pumps, one for a water feature and one for the filter system. Filtration is a 60 sq. ft DE, which I recently back-washed. The back-wash exit is piped from the filter immediately below ground with a sight glass - my assumption is it is ran directly to a drain. The pool is fresh water, but has a non-functioning SWG installed as well as a liquid chlorinator.
Chemistry wise, I am using a TF-100 test kit, Ive been recording 7.7 pH, 120 TA, 360 CH, 0 BOR (although am planning to convert to borates after I get my TA and pH down . The big issue I have is that my CYA is in the 180 range (as such I've been maintaining FC around 15+, and immedately stopped using trichlor upon closing on the house). I have seen as much as 1 CC usually only when the pool has been used.
My intention is to get my pool in line with the TFP method, but I would greatly appreciate the opinions of some of the experts her, and I've done some searching of the Forum without much luck to find anything on this topic...
With my CYA so high, is it practical to martian the pool where its at using liquid chlorine only and let it drift down over time via rain and splash-out?
If I need to replace some of the water in my pool, what is the most efficient way to do this? Some have suggested to me that CYA floats, so perhaps could I brush the pool, fill from the bottom and drain from the overflow (with pump off), in order to lower the CYA with the least amount of water possible? is it ok to continually drain from the overflow, or should I drain from the skimmer?
Second- Ive put a good deal of 20 baume Muriatic acid in my pool, and do not seem to be getting the results the calculator predicts. Just yesterday I put ~1cup in the pool, brushed it, circulated for 1 hour... and recorded a drop from 7.8 to 7.7. Any thoughts on what I may be getting wrong?
