Hi and thanks for looking.
I recently got a used hot tub, it seemed in good condition. The heater didn't work so replaced the element. It had been sitting for a whole so I did a purge twice as per the instructions on the bottle to clear out the bio film.
Flushed a couple ofbtimes with clean water then filled it up and Started it up and heated up to 38c , put 2 bromine tablets in a floater shocked it with not chlorine shock. Bromine and ph were within the right range. Had a soak in it and got a little bit of foam. Next night a lot of foam and the water was fizzing qhen the jets were on. If you turn the jets off within a few seconds the foam and fizzing disappears.
Checked the levels and all with in the ranges.
Qhen I did the first purge some gunk came out but the second one nothing came out.
This is my first time to have a hot tub. What have I done wrong?
I have read about doing a purge and then putting bleach in to kill any bugs. So might try that
