First off Hello to everyone and thanks to those who have provided valuable information on this forum. I'm new to the world of Spa ownership and have had a Tuff Spa TT450 Platinum (350 Gallon) for about 4 months now. Over the last month or so I've been reading about the TFP Chlorine method and figured I'd give it a shot. I purged the spa with Ahh-Some, drained, cleaned and refilled the tub. Initial readings using a TF100 test set are as follows. CH 190, TA 260, FC 0 as I am on well water. Over the last 1 1/2 days I have added dry acid until I've gotten the TA to 60 PPM but the problem I'm having if it is a problem is that the PH has never gotten below 7.9. So I have a couple of questions that I was hoping some of you wizards might be able to answer for me.
1. Should I continue to drop the TA to see if I can get the PH to drop or leave it as it is. If I continue to drop the TA to see a PH drop how far should I go.
2. I ordered some Boric Acid to help stabilize the PH once I get it where it needs to be. In the thread How TO Use Chlorine it talks about adding Borates to 50ppm to help stabilize PH. Question I have is how do you know you have 50ppm (is there somehow to test for it) and if not how do you know you have enough.
Any help you could provide would be greatly appreciated as I'm a holding point as I don't want to add any dichlor until I have the TA and PH where it should be. Thanks in advance.
