  3. Genesis System - Ta And Ph Questions..

    in Hot Tub Water Chemistry

    Posted

    I am not sure what BOOST is, but REFRESH is a non-chlorine shock (MPS). My genesis unit is set to 7 and my filtration is set to 8 hours per day and I'm getting about 2.5 PPM of bromine which is pretty good I think. One thing I just noticed though is that my sodium bromide concentration has dropped down to about 1500PM (7.2 on the scale). Not sure how that happened since it has only been in use for about 2 months.

  4. Sodium Bromide Levels

    TorontoTubber,

    Sounds like your Arctic guy put in the same thing I have - the Genesis system. Your sodium bromide level is a bit high, but should be fine. Get the Taylor K-2106 test kit and check your bromine levels. I keep mine right around 3-PPM which I achieve with a "7" setting on the genesis. I also have the Peak Ozone system. Only complaint I have is that pH keeps rising and I'm needing to add adjust-down fairly regularly to rectify it.

    My advice on adjusting the genesis is to start to 10, run it a few days and see where your levels are. Knock it down one notch every couple days until you find it's in your range. Don't turn it down several notches all at once.

  7. Genesis System - Ta And Ph Questions..

    Hi there, I was hoping someone could help me fix my TA and pH issues.

    I have an Arctic Spa with a Peak Ozone system and just recently had the Genesis system installed. After filling my tub, the TA and pH were in the correct ranges, so I added the jugs of sodium bromide and did the initial shock with MPS as per the instructions.

    After letting it run for a day or so, my bromine levels were fairly high (understandable since the system was set to 10), and my pH seemed to go through the roof (8+ using Taylor K-2005). The TA was still nicely in the range though.

    I turned down the Genesis setting gradually as they suggest and I'm able to maintain a 2-3 PPM bromine level, which I think is fine in combination with the ozone. However, after a few attempts to push it down using the "adjust down" product I was supplied, the pH keeps going back up. It would look good for a day, but then shoot up again. I don't want to add much more 'down' since the TA keeps dropping (down to 80-90 now).. They supplied a "perfect balance" product to push up TA, but won't that increase pH as well?

    My neighbor with Genesis (same water supply, but different tub and no ozone) was told by his dealer that keeping TA in line is more important than pH and to not worry about high pH. He can't seem to keep enough bromine in his tub and his setting is always on 10. Does the high pH interfere with the bromine production?

    Any ideas?

  9. Nature2 Grit...

    I have an Arctic spa with the Peak Ozone system. After giving up on bromine, I've been using the Nature2 sticks for the last year or so. Those work great for the first month, but water seemed to turn bad very quickly after that. Water ends up mostly clear, but very musty smelling. I was using the Arctic Refresh (MPS) to shock occasionally, and Lithium at startup and once or twice if there was a heavy load (which didn't happen very often). If anything I'd say there was very light usage over the winter.

    What I need help with, is that while using Nature2 I started getting "gritty" deposits on my shell and on the jet dials.. Any idea what this is and how I can get rid of it? There's no discoloration and calcium hardness seems to be in the right range.

    I'm giving up on Nature2 since I don't think it does much and switching to a Genesys bromine generator later this month, but I want to fix this grittyness on my shell. It does slowly come off with a cleaning brush, but I'm not that patient... Ideas?
