I’m confused and can use some direction. We recently brought a 2007 Envoy that is equipped with an ozonater, N2 cartridge, and holds 450 gallons. Our dealer set us up and got us going with balanced water…I assume. The dealer suggested we use 1 tbsp of MPS after each soak and an ounce of dichlor a week to shock. Through this site I’m taking a crash course on proper water balance and maintenance, thus brought the Taylor K-2006. My first reading was TA – 50ppm, PH – 7.4, CH 220. I attempted to bring my TA up and the next thing I know my readings are TA 130, PH at least 8.0, and CH 250. Working Saturday & most of Sunday to get the water balanced and a chlorine reserve and weekly MPS shock, my readings at the end of Sunday were …TA – 90ppm, PH – 7.6, CH 240, FC – 6.2 (I added a lot of dichlor with hopes of some left over until the next day), CC - .6, CYA 45 ppm.
It’s been days and I wanna soak! Therefore, I tested once more this morning and I have…TA 90 ppm, PH 7.4, CH 250ppm, CYA 50 ppm, FC 2.2 ppm, CC .8ppm. Please note I also have a hard time maintaining chlorine until the next day.
With a FC of 2.2ppm and a CC of .8ppm, is there something ugly festering in water? Is this a false CC reading due to MPS? What’s considered too high on CYA reading? How much MPS do you recommend weekly? How much dichlor do I add to maintain a residual of 3 – 5 ppm? What do you think of my latest water test numbers? I think I tried to fix too much at one time and now I’m confused. Please guide.
