Ok, seems like I've got all the info I need to start out. Thanks very much guys.

Ok, understood on all points. I think my initial plan will be to use the system with the AOP running and not use the Nature2 cartridge to start (as I would like to try bromine). With the AOP system running, but still following sanitation standards, I'm going to shoot for a resting bromine reading at the 3-4ppm level (which seems to be the low-end of still-acceptable/normal levels). Further questions: - I've read that ozone generators can cause enough ozone that, after de-gassing, cover degradation may occur. Does the AOP system lead to less of the ozone byproduct residual in the water and therefore reduce this harmful effect? Is there anything I can do pro-actively to maintain the life of my cover? I've got an End2End rollup cover (https://www.end2endswimspacovers.com/) on order as my physical disability requires something very easy for me to operate and I'd like to prolong its life as much as possible since it was quite expensive. - I can't remember where I saw this mentioned, but I thought I saw something about floaters for bromine tabs not being recommended as they concentrate the bromine by the spa filters/equipment? Is this an actual concern? Thanks for the clarifications.

Hi, I've spent a few days reading all the stickied (and other) posts here. I haven't been able to find much on my question searching the forum, so I'm hesitantly posting a new thread.. I'm a first time spa owner with a new TidalFit swim spa (1,600 gallons) about to be installed. It comes with an AOP combined with a Nature2 system. There doesn't seem to be much info on AOP systems out there that discuss chemical dosing in any detail. I understand that it is an ozone system plus UV to create hydroxyl radicals. The configuration reduces the amount of ozone that ends up in general spa water, which prevents cover degradation, etc from the off-gassing. 'm assuming a lot of this is marketing, but i've read that it does mean i can use a lower amount of chlorine/bromine to keep my system safe. I was planning on following the sticked thread from @waterbear which details out quite thoroughly how to keep my system balanced with bromine. Some questions: 1) There seems to be debate as to whether bromine is compatible with Nature2. Nature2's website itself states that it is, but there are many posts throughout different web forums stating otherwise. The Nature2 manual states to use chlorine, but also doesn't mention you can't use bromine. Any specific thoughts here? I am fine going with chlorine if that's better/necessary. 2) Is it true that I can use a lower resting level of bromine/chorine and still have an effective/safe system with the AOP running? Something in 1 ppm range? It's my understanding that the AOP system is not the same as a standalone ozone generator as the end result hydroxyl radicals and not a long tube of ozone-injected water. An AOP system is purported to actually reduce the need for standard levels of sanitizer. Any other comments on AOP for the spa in general? I know the swim spa capacity at 1,600 gallons will require 4 times+ more chemical than a standard spa, and i'm hoping the AOP system means I can use 1/2 that or less compared to a standard sized spa without an AOP system. Or is this all marketing crap and I should use the standard chemical rates....? Thanks in advance... - Mike
