I have a question. I have found that using the part at the bottom of the pool calculator effects of pool calculator is a lot better for me. When I fill in the top and say I want to change pH level from 7.8 to 7.4 and I feel out all other test with the same number in now and target, I will get a different amount in the top part vs bottom part in the effects section.
In the top part I will only want to affect pH and drop it to 7.4 from 7.8, 37 oz to be exact. In the top part though it will say add like 70 oz of acid, which in the bottom part says it will drop about .76.
Am I doing something wrong here.
Is there anyone else who uses just the bottom part when you need to change individual stuff like pH levels or chlorine?
