I am planning to open the pool for the season in the next week and could use some chemistry advise on what to improve over last season.
I am heading into my third season as a pool owner and after fighting high CYA on tablets, with the help of TFP, at the start of last season I switched to liquid chlorine (12.5% from leslies). I drained my pool down 50% and brought my CYA to around 70 at the start of last summer. I started last season with a TA of 110. CH around 280. Ph of 7.4.
I maintained FC at 4 to 5 ppm all season using fresh gallons of chlorine. I shock every couple weeks using cal hypo from leslies or in the swim. The issue was PH seemed to float up to 7.8 very often and 8.0 if left un-adjusted for a week. I had to lower PH using dry acid weekly. This would last a couple days. Then PH would rise from the chlorine. The acid additions led to the TA dropping to as low as 50 during the season so I would lower the PH with dry acid to 7.4, then the following day raise the TA using baking soda. Within 24 hours after that I would be back to 7.8 ph but with the higher TA.
The water usually felt less comfortable than it had when the pool was on tablets. I assumed it was the higher PH and lower TA at times. When the PH got too high I had metal staining on my white steps so I started using jacks blue stuff to keep that at bay. I have domestic water but it is sourced from wells in my town.
I felt like I was chasing my tail all season with 4 cup measures of dry acid and boxes of baking soda. I have a Taylor K-2006 kit with reagents that are not expired. I test PH and FC every 24 to 48 hours max. I closed the pool with a TA of 70 if I was lucky and a PH of 7.6.
I know that liquid chlorine is supposed to only temporarily raise PH but it did not seem to the be the case for me. I do keep one of the return jets pointed at the surface for water movement. Could that alone be the cause of the high PH?
A friend suggested to add borax to the pool but I have not researched yet.
I hope to get my CYA down to closer to 50 at the start of this season but other than that any suggestions from the TFP forum would be greatly appreciated!
