Brand new tub, had it less than a week, been in it every night, along with friends, relatives, etc. It's fantastic.
Been testing the water every day, sometimes multiple times a day, just to get used to how things behave.
Using the LaMotte InstaTest 3 strips that came with the tub and adding ProTech Dy-Chlor II, which also came with the tub.
Alk has been holding a fairly steady 80, and pH has been around 7.2 or slightly higher, but FCl has vaired a lot, usually on the low to none side. I'm getting a bit of foam too when the jets are on high.
Is this because of all the usage? Does the thing eat the chlorine and need to be fed this much when we use it a lot?
Since it is brand new, should I be looking to use that Spa System Flush?
Thanks for the advice and the warm welcome!
