Thanks to this forum, my pool and spa are looking splendid, and after learning about testing and what levels to watch I need some advice.
Since I have two separate bodies of water, I don't want to spend 30 minutes testing everything three days a week during the summer. So I've only been testing FC, CC, and PH; I use bleach and Muriatic Acid for adjustments . I've tested CH and it's within range and since I'm not adding any more calcium to the water, it shouldn't move. I've tested the CYA and although it's high (I make sure my FC is within a higher range), I know it's not going to move since I'm not adding any more to the water.
So when I test my three levels I adjust the chlorine with bleach as needed, and if my PH is too high I then check my Alkalinity. If my alkalinity is good then I don't worry about PH because i know the Alkalinity will bring it into range, but if it's high I adjust with Muriatic Acid and aerate.
This method seems to be working great and it makes sense to me with my understanding of how the chemicals work with each other, but I'm new to pool ownership and would like any advice from the more experienced members on whether I'm missing something or not.
Thank you for your help!
