Ok, I'm just thinking outloud here. I'm very new to all this and you've all provided a lot of info. so far. So, feel free to chime in and correct me where I'm wrong and answer my questions and convince me and all that.
I have a frog. A few days ago, after much research, I decided to stop using it and probably go BBB. However, the "convenience" of it REALLY appeals to me. So, I'm searching for ways to be able to keep using it. But, at the same time, I don't want to cause myself more trouble later.
I have high CYA of 85 (as per the pool store, 90 according to my readings at home). The PS says it's fine, don't worry about it. I said "yeah, but doesn't the frog keep adding to the CYA" he replies with "no more than any other chlorine source". I did not mention to him that I was considering bleach. He said it's fine, no need to drain/refill. He even goes as far as to say I can turn down my frog because I don't need my FC as high as it is (3.1)
So, who do I believe? I know he's trying to sell me something and TFP isn't, but it's hard not to trust those "in the business".
Here are my test results. I took the water to 2 PS's today as well as did my own CYA test.
PS#1... (drop test)
PS#2... (computerized test)
My CYA = 90
Now, it's not going to be very costly for me to do a drain/refill as I have a well. I could probably do it slowly too if I wanted. So, here's my options.
Assume Rain, water additions will lower or at least keep CYA where it is.
Rain/water addition will probably lower CYA over time.
Lose money on frog we already bought
Save money on chemicals
Looking for any insight.
