    Poolsmith CO2 injection for pH control

    In my area, buying a full tank without an exchange from Airgas was not much different in price than buying a new tank and getting it filled at the fire safety place, and Airgas's exchange price was about the same as the refill price. I didn't find the cheaper exchange price at another place in...

    Poolsmith CO2 injection for pH control

    Around here, the only places I've found that will do refills are fire safety companies. Welding supplies will only do tank exchanges. The cheapest refill price I've found is $45/tank (20 lb. tank). Cheapest exchange is $25 (most are higher). I did a refill because I have nice new tanks and I...

    Poolsmith CO2 injection for pH control

    Update: refilled the tanks this morning, so three 20 pound cyclinders lasted just short of 5 months.

    Poolsmith CO2 injection for pH control

    A point worth mentioning about the Poolsmith controller, it has some idea of elapsed time (so for example it knows when approximately 24 hours have passed since the start of the last injection cycle), but it doesn't have a clock (so no concept of date and time). This is relevant because if you...

    Hayward OmniLogic schedule issue

    So the app and the controller agree, which means there is no communications problems between the app and controller. If I'm understanding your problem, whatever speed you have manually set (regardless of whether it is from the app or the controller directly) is the speed the pump runs at when...

    Hayward OmniLogic schedule issue

    The app is essentially a wireless remote for the control panel. The app communicates with Hayward servers over the internet, which in turn communicates with the control panel, which then communicates to the equipment. The app does not directly communicate with the equipment. Thus, whatever...

    Hayward OmniLogic schedule issue

    I would start with verifying that your pump is configured properly in the controller. I don't have the PL controller, but on my Omnilogic there is a Configuration Wizard on the control panel where the pump parameters are set up. For example, type of pump (which should be variable speed), the...

    Poolsmith CO2 injection for pH control

    Switched over to the third tank this morning, so adjusting for the time the system was off-line, the second tank last just over 7 weeks. So I expect I'll be needing to refill the tanks around labor day, which would be right around five months since I first turned the system on. So far, so good.

    Poolsmith CO2 injection for pH control

    The best local price for CO2 refills I have found is $25 for a 20 lb tank. For my pool, that translates to a yearly cost of about $175 for CO2. At my previous acid demand rate, I needed about 25 gallons of acid each year at about $6/gallon, about $150. So pH control using CO2 is slightly more...

    Poolsmith CO2 injection for pH control

    Update: my TA rose back up to 80 pretty soon after I had lowered it to 70 using MA. It has stabilized there, and I'm just letting it be. We have been getting much more regular rainfall since the drier conditions ended a few weeks ago so there probably hasn't been much water added via the...

    Hayward OmniLogic R4.1.0 MSP Released - Remote Internet Update - No release notes at all

    It is on the website now, that's where I've been checking. Really not much unless you have a heat pump or solar. Think I will skip this one.

    OmniLogic 4.1.0, but can’t find release notes

    No release notes yet that I can find. I haven't read about anyone who has upgraded having issues, but I also have not read anything about what the differences are compared to 4.0.1. So I decided to wait for more information before upgrading.
