I recently set up a new hot tub. Infinity 350 gal (Costco) with, two water pumps, bypass cartridge filtering, and a waterfall (seems a silly addition). Finished the 50A GFI wiring three weeks ago and have been using it since then.
I have been reading http://www.troublefreepool.com/ for a bit and have learned a lot. I appreciate the good information I have received in responses to my questions. I am in central NC and have city water which is relatively soft (surface water). I decided to try BBB. Water temp is currently 103* F.
After about 2 weeks I bought a box of 20 Mule Team Borax. I found that the borax did improved the appearance and feel of the water. Not sure how to describe the effect on feel.
I'm curious about exactly what borax is doing beyond buffering. Does it change the surface tension, viscosity, index of refraction? All googling yielded is that borax is used as a “bath salt”.
Does anyone have any thoughts about what exactly the borax is doing that changes the appearance and feel?
