Installed an indoor fiberglass swim spa and I'm finally getting around to plumbing the thing. Pool manufacturer provided the 1 hp pump, 75 sq. ft. cartridge filter and the optional 0.35 g/hr ozonator (0.70 g/hr if I use a dryer). After getting everything, I researched ozone and see that you still need chlorine and the ozone is only effective on the filtered water. Of course, with the oversized pump, it will only need 30 minutes for one turnover, so it became clear that I was being guided by a pool manufacturer that knows nothing about filtration systems.
I do have some experience with an indoor pool this size, but I always had trouble with CC with a very low use pool. But this is a future thread and only explains the logic of buying the ozonator.
Anyway, the pool has no jets, no water feature, no vacuum requirements and just needs a filtration system. My current thought is to ditch the 1 hp pump and replace it with a 1/8 hp Waterway Iron Might, which would cost about 40 cents a day to run 24/7 and plenty of turnovers. My first thought was a dual speed 3/4 hp, but I started to doubt I would ever run it at full speed. The only downside I can come up with using the small pump is the effectiveness of the skimmer. Again, this is a low use pool to be used almost exclusively by myself so that may not be as important.
Does anyone see anything wrong with using a 1/8 hp pump on a 2,600 gal. pool?
My next concern is the ozonator. I'm not sure if I should bother installing it or not. I know I would need an air dryer and contact chamber to have any effect at all. I'm concerned about CC with the indoor pool from past experience, but maybe having some CYA (yes, I have been reading this site) will help. I thought about using a SWG with the ozonator, because of possible benefits after reading someone's patent, but Richard (chem geek) pointed out the flaws with the equations. And I also see that salt can cause corrosion in some cases. So, here I am sitting with this paper weight (ozonator) trying to figure out is it worth it or not to install.
Other info: pool temp will be 79-80 degrees and most likely be using a floating cover to reduce evaporation. It also has a titanium heat exchanger.
Any suggestions about pump size, ozinator and/or SWG would be appreciated.
