Newbie here and glad I found this forum. We have new spa (less than 1 month old) and had been using the Leisure Time Bromine System that came with it. While I was gone the, the 24 hr circ pump failed to operate for a few days and I returned to a green slimy hot tub. Since then, we've added about 8 oz 6% household bleach, balanced the water, and MPS shocked it twice.
It is still pea soup - but is not slimy.
oh perhaps I should have mentioned it foams too...
which does subside with the defoamer that came in the start up kit.
This forum has been a great chemistry refresher and I've ordered the 2106 kit as the test strips are pretty much useless, even with the app that reads them. Bromine levels don't seem to be read reliably by the strips - or the strip color develops very quickly - readings vary between 0 and 15.
Currently, I believe we have brought the pH and alkalinity down to 7.4 by adding both white vinegar (at first) then when this wasn't working fast enough 10% sulfuric acid (spa down). We had some residual solids in the floater, but I added three more bromine pucks to them.
And, last piece of info, we has just started WatersChoice, but as I said this is only a 1 month old spa and we've only added the 3 capfuls before we lost circ pump for a few days (which also kills the ozone generator).
Any suggestions or do we need to drain an fill?
