After fighting with pale green, yet clear water for the last couple of weeks, we emptied and cleaned the tub today... We had one or two bouts of cloudy water a month or so ago after enjoying clear water for a few weeks. After using SpaKleer, the cloudy water cleared, but we could never get rid of the green hue.
I used TSP to scrub it down and ran it when it was 2/3 full to flush the lines. The instructions say not to power it up until the filter chamber is at least half full. Then drain, rinse, rinse, drain, rinse, etc.
Next, after filling it, I powered it up, it ran through the powerup cycles, including the recirc pump & ozone. It looks good, other than we still have a faint green hue to the water... must be our spring well water. It looks much much better than the old did, however.
At the moment, it's way past bedtime.
The only chemical I added tonite was metal gone. I understand the chemicals work better when the water is at least 80° so I'll wait until tomorrow after the water temp comes up from it's current 60°.
Tomorrow, I'll install the new filter (currently using the cleaned original) test the numbers, then add the bromine reserve and bring up the calcium hardness as I know it'll be about 100 where it should be about 250.
Then add the bromine floater and wait... then adjust PH/alk...
What is your process for bringing up a new spa?
Why did the spa shop recommend I soak the filter for 8-24 hours in TSP before installing it?
Thanks in advance!
