We are in the final stages before actual construction starts on our 17'x34' free form sports (3.5'/5.5'/5') 13K gallon w/ Paramount infloor, River Rok, heater, w/ DE filter. The PB has spec'd an ozone w/ UV system @ $1500. After spending several hours on this site I'm finding there seems to be very little support for ozone. This has me seconding guessing the PB and considering going with a SWG.
Most of the threads I've read are from 2010-2013. Has there been any change in the technology from then to now that might have changed the consensus from a few years ago against ozone? The PB will do salt if we want, but the concern for them and salt was the negative impact on decking salt has. The impression we got from the PB was Ozone/UV was the latest/greatest and SWG was on it's way out. Even with ozone/uv they spec'd a small chlorinator as part of the build.
Initially I thought ozone w/ UV was two separate processes, now I am seeing that there are 2 technologies ozone through corona discharge and ozone through UV. The technical papers I've read are showing that ozone level generated through UV is much lower than by CD. The thought was we would only be running the pump 4 hours a day, making ozone seem less and less desirable since we aren't getting any benefit from ozone with the pump off.
