I hope you got the pictures. Test kit is due early next week. Want to make sure you noticed I have an UltraPure Uv Ozone generator also. Didn't know this and had no information from builder, but went online to get product info. It's a UPP25, good for up to 25,000g pools, generating 0.146 gm/hr. Seems a bit of an overkill, but will reduce chlorine need and extend the life of the SWCG. Currently have IntelliChlor at only 20% on. Don't think UltraPure would be part of why the PH rises from what I've read. Thinking my pool just runs at higher PH w/o any borax. I have all of he materials, borax & acid, but am waiting for the test kit before I do anything. From test strips, it looks like I have NO CYA and TA is 100 to 120. If I understand the info from the Forum, may need to lower TA before I add borax. I think that will be easy since I have the jets in the spa and can have the spa water flow into the pool while running the jets.
