I have a 23K In-Ground pool, with a 7 ton rock waterfall. Freeze guard was on most of the last two weeks and my TA dropped to 50. I added 13lbs baking soda. Next week, TA dropped to 60. added another 13lbs of baking soda. I have an 2 tank intellichem setup, which injects liquid chlorine and Muratic acid as needed. I went through about 2 gallons of muratic acid each of those last two weeks. I can only assume that the pH rose due to the aeration effect of the waterfalls on constant during freezing weather, and the Muratic acid consumed my TA.
Is this normal or I am chasing my tail here?
I have a plaster bottom, Rock waterfalls, 2 SVRS intelliflow pumps, one for filtration, one for waterfalls, cartridge filter, ozonator 2 skimmers, Pentair heat pump.
Water is checked 3 times a week- in summer, I consumed approximately 3-4 gallons of liquid chlorine a week, and about 2 gallons of muratic acid. Installed the intellichem and ever since it was installed, I have been filling muratic acid and dosing the pool with baking soda. My friend, who also subscribed to this forum, had his pool operating all summer, but switch to liquid chlorine mid summer- still says his TA stays fine, and he hasn't had to add any baking soda to his pool. I'm just wondering if I'm screwing up. I'm a new pool owner, just built last year, and I'm in a lawsuit with my builder, so he's no help..... Pool store says my water's great every time I go in, but thinking they may be laughing all the time, because I keep buying products when I run out.
Calcium hardness 360
(Been working to get the hardness down, and the CYA down- the pool builder put the CYA in (too much in my opinion, and they installed an erosion feeder, using triclor tabs). After they left me, I had the intellichem system installed, but the technician who installed it had little/no experience with it. Pentair Tech support set me up, and they are borderline on whether my consumption of Sodium Bicarbonate/Muratic acid is "in-line" with what I should be expect.
Water is beautiful, easy enough to deal with, just wondering if my chemical consumption/costs could be lowered without sacrificing on water quality, safety and keep my pool and equipment in the best condition.
