So I took over the pool about a week ago, it has been up and running for about 3 to 4 weeks and with all of the holidays, I wanted to start taking over because I knew that service will be diminishing.
So intial Test:
So, I went to Leslies (big mistake) to get ALOT of chemicals, due to the pool size and pool math calculator. I was armed with reading TFP for about a year, so I thought I could get in and get out with out getting hosed. I know that a lot of post talk about how the pool stores are more expensive, but I thought, for my time and convinence I will get what I need to now, and get additional chemicals at the recommended locations. I didn't think that the difffences would be worth the extra trips.
First thought when I took the pool over was. Man, that CYA is much lower than I would thought, second, I was very surprised, being a new pebble/plaster pool that the CH was so low.
So using poolcalc that is on TFP, I went and bought what I needed. When I went in I was surprised that not everything had clear labels of what exactly was inside. I had to look at the MSDS online for several products that she recommended. Eventually, much longer than anticipated, walked out with 300 dollars worth of muratic acid, Cal Hypo, CaCL, CYA and Bicarb (just in case).
After several days of adding, I am at
Things I didn't know.
CaCl gets hot, very very hot when mixed in a 5 gallon bucket. The bucket started to get soft.
Never lay your stirring stick on the stained concrete
The acid is no joke. I splashed more than I thought due to the fact I didn't take the seal completely off. (also splash concrete with water before pouring chemicals seems to be a good idea.
Things I cant explain:
It took over 180oz of muratic acid to decrease the pH, surprisingly, and I do not know why, the TA did not change. I know salt systems increase the ph due to CO2 displacement via H, and we have had the freeze protection on a lot which is a waterfall aerating a lot, so I am not surprised the PH is up, but I thought the TA would drop some. The PH did not budge until the last 40oz added.
Things I knew but didn't know:
CaCl at walmart as de icer was about 1/4 the price . Knew it would be cheaper, but not that much difference. Lowes muratic acid was about half.
Need to raise CYA up, and get my calcium up as well, would like my TA to come down because I am going to use borates, in about a month or two, once I can get everything where I want it to be. Hopefully the high acid demand is the new plaster, or the freeze protection mode, if not I am getting a stenner pump before myself and the concrete looks like a dalmation.
