Borates

[gmdodt]

About to drain and refill tub.  Want to try adding borates this time

Anyone tell me the specific product I need.  I think I prefer boric acid so I only have to bother with one thing

I use @ease chlorine (spa frog) and a mineral stick.  Should I still do 50ppm borate?

TA 50 when I do this? PH 7.6 ideally.. correct?  Balance tub then had borates

If you are going to use borates, then yes, 50ppm or above would be the ideal amount.  ProTeam Gentle Spa is the only one I am familiar with, but I am sure there are others.  In my opinion, a total alkalinity of 50ppm is on the low side.  I prefer at least 70-80ppm.  Most chemical manufacturers and hot tub manufacturers want alkalinity between 80-120ppm and some, like BioGuard, prefer 125-150.

I would do borates before pH and alkalinity as not all borate products are pH neutral.

i was under the understanding boric acid was near ph nuetral and there were non-tub labelled products, like rodent killer that could essentially be used

I can't comment on anything not specifically meant for a pool or hot tub.  ProTeam Gentle Spa is pretty close to pH neutral, but I know there are others that have a high pH.

Ordered straight boric acid. 99.9% pure. Hope its the right stuff.
