We have a hot tub/swim spa combination and have had it for a month now. The hot tub side is 425 gal and the swim spa side is 2100 gal. The hot tub temperature is kept around 100 while the swim side is at 90. The cover is on both sides almost all of the time. The hot tub gets the most use (in this weather), generally after dark. So there is little or no sunlight hitting the water.
The default filter settings have the pumps running two hours a day in the evening. I can change this schedule, but I don't know what it should be.
When I check the swim side water, the chemical levels tend to read in expected ranges, except the FC is usually zero. Then I add chlorine (currently using the dichlor granules sold by the pool store, have read about using bleach and will be adjusting that) This could be because the swim side goes days without me checking anything. Again, this is new and I'm not sure what I should be doing or when.
The hot tub side is... well, it's a hot mess. The water is consistently cloudy, the FC keeps dropping to zero despite being adjusted and shocked, the pH bounces all over the place and it's foamy. When I got my TF Test Kit (just came in a few days ago), I measured TA at 50. I weighed out what should have been the correct amount of alkalinity increaser (still using the chemicals the pool store sold me, I know I should be using baking soda going forward) based on the TA measurement and the spa size. Despite that, the TA is now reading around 150. Yesterday, the pH was low (below the bottom of the scale) so I raised it. Then this morning, the pH was reading about 8.4 so I added pH decreased (again, the pool store chemicals). I got the pH to read closer to 7.8. I have no idea what it will be next time. Despite adjusting the TA, the pH continues to bounce. Today after adjusting the pH I added a non-chlorine shock and after about 30 minutes a few tablespoons of the dichlor granules. I'll check it later. It's still cloudy. CYA tested at 10. I don't have anything on hand to adjust that right now.
We are about to leave town for a week so the system will not be touched. No one will be checking or adjusting chemicals. I will be buying the recommended chemicals when I return. I don't know whether to allow the neighbors to use the hot tub while we're gone. I'm not sure the water quality is in a good enough place, and they don't know how test or adjust it.
Any recommendations?? I know that's a lot.
