Welcome to our forum.
What exactly does this system do? I thought it generated chlorine from the salt in the water with the assistance of the system, but so far everytime I test the water the chlorine is low and I need to add some. The tub is a week old, and PH has been on the high side but I keep adding PH reducer a little at a time. Salt level is good, and ACE says it is functioning properly and set to level 5.Am I missing something?
If you don't use any Cyanuric Acid (CYA) aka stabilizer or conditioner in the water, then the active chlorine level will be much too high. Free Chlorine (FC) does NOT tell you the active chlorine level that oxidizes swimsuits, skin, and hair as well as bather waste, hot tub covers, and disinfects. With CYA in the water, it significantly moderates chlorine's strength. I suggest a level of around 30-40 ppm CYA. You can add it via pure CYA that dissolves slowly or you can use Dichlor in the spa for a while since for every 10 ppm FC added by Dichlor it also increases CYA by 9 ppm. With Dichlor, don't add it all at once (i.e. not 30-40 ppm) since the chlorine level would then be too high.The ACE system outputs both chlorine similar to a saltwater chlorine generator (SWCG) but also outputs very short-lived and powerful oxidizers called hydroxyl radicals. The salt level is lower than in a normal SWCG spa (say one that uses the ControlOMatic Technichlor which uses 2000 ppm) and the Calcium Hardness (CH) level must be very low because the special boron-doped diamond electrodes used in the system are very sensitive to developing calcium carbonate scale.As for the chlorine level itself, you should be fine so long as it is at a measurable level, 1 ppm FC or so should be OK, though with the CYA in the water even higher levels won't be that noticeable, but most people prefer soaking in not more than 2 ppm FC so that they don't notice the chlorine or chloramine smell.
Well I am sure glad that ACE system cuts down on having to use any chemicals..
