Hi all,
Just finished first fill on newly installed AG pool. Install date was 5/16 and finally full enough to start pump on 5/26. Filled from sandpoint well, and everything looked great until the last couple days of filling, then the water turned greenish/brown, and I want to make sure I'm headed in the right direction to resolve.
Upon first startup of pump, I added PH down prior to any other chemicals to get my PH levels to 7.5-7.6. I then installed the mineral cartridge and V-pack (dichlor I believe) and shocked the pool overnight with sodium hypochlorite. Instructions for the mineral cartridge say to balance PH and then install prior to shock levels of chlorine, and I installed the V-pack at the same time in order to start building some CYA.
Currently FC is at 4, down from 5 this morning when I started manually adding CYA prior to sunrise.
My PH remains at 7.5 but TA is between 150-180, I say between because the color matches the 180 but is not super concentrated on the color tile of the test strip.
My water does not have a strong chlorine smell, and I can see the liner on bottom (54" depth), but still have a greenish-brown tint to the water, with some light slime coating on the skimmer parts. I have the flapper disc vacuum running but not sure that it's moved on it's own in the last 5 hours, so I don't anticipate that the vacuum is going to be a great help but wanted to try to get leaves and debris off the bottom that built up during filling.
Since there is a descent amount of FC in the water, and I'm still injecting chlorine, my current thought is that I need to get TA down to ~75 or so and maintain that. If I still have the stained water then I will do a SLAM.
It seems to me that I have a long road of using muriatic acid to lower PH/TA, and then raising PH back up to do it again. From what I understand, if I use 120 oz. of muriatic acid to lower PH to 7.0, TA will only be 22 ppm lower than it is now. What are my alternative options, how else can I cut my TA in half without drastically affecting PH or other chemicals?
I have several different kinds of test strips, but that is the limit of my current testing capabilities. Also, I currently only have the starter pack of chemicals that came with the pool. I will be going to town tomorrow to buy more, and hopeful that there are some suggestions here as to best approach to getting clear water.
