Prism tub, need help!
Hot tub dummy:
I ended up draining about 6 inches of the tub and refilled it. The salt level is down towards the bottom of the green. I have the salt level set to 10. I'm still not getting a reading on the test strip of any chlorine. I put a vanishing act pillow in there to lower hardness but I'm not totally sure where to put it. I put it at the bottom where I think is a suction return on the side in the footwell, there are five of them? Its been in there 12 hours and then flipped but its not changing the hardness, maybe wrong place? I put the setting on vanishing act on tub also.
castletonia:
What was the calcium hardness to begin with? 12 hours is not enough for time for Vanishing Act and depending on how hard your water actually is, it may take multiple or the XL version. The salt system takes time to produce chlorine. Again, without knowing hardness and phosphate levels I have no idea how efficiently the system will work or whether you are wasting your time and you should start over.
Hot tub dummy:
Hardness is pretty much at 250 and has stayed there, should I put another pillow in? Does it matter where I put the pillows?
castletonia:
You will need the Vanishing Act XL. In your owners manual it indicates which suction return to put it by. In the future, I would invest in a portable water softener. The cost is a bit more upfront but it will save you money in the long term.

I got water soft by using two vanishing act pillows, everything is in balance but I can’t get a chlorine reading on test strip, I’ve added a couple cap fulls of chlorine but still nothing, salt string is on 10, do I keep adding until it shows up?
