    What are you supplying the water with to the calcium reactor?

    Jeff from Lifereef, who has been super helpful, got me hooked up with the CaRx extension tube (holds more media) and a Rio 180 for the intake pump. Something like 185 gph for the feed pump.

    So....now that I am no longer using the Apex Dos for dosing 2 part, I think I might set it up for Auto Water Changes.

    Today I carefully measured my SW mixing bin at 24g and made a mark. My salt mix (Instant Ocean) says 1/2 cup per gal so I mixed that all in. I'm going to let the pump circulate that for a while, then I want to test the SG, Alk, Cal, and Mg so I have a baseline and then add to the mix to get my desired levels.

    I'm thinking along the lines of 2 gal swapped out per day, I'm sitting at 225g of total water volume. Thoughts? More, Less, about right??

    I am terrible at regular water changes. My last box of salt mix, which makes 200g, lasted me 12 months, so I did about 8 water changes at 25g each in 12 months. If I can mix up fresh mix of salt about every 12 days I should be good, that would be about 30 water changes at 24g each (2g per day takes 12 days to use up my 24g, 365/12 = 30.4 water changes.)

    Thoughts/suggestions?

    Seems like a cool idea. I've seen plenty of threads with people doing AWC successfully. Personally, I would want multiple layers of redundancy with float switches and leak detection alarms to feel totally comfortable with it. It's definitely achievable though.

    I would do 3-4 gallons a day since a 10% weekly change is a pretty good target IME.

    I would highly suggest using failsafes such as high level sump, low level sump, low level NSW reservoir, tank conductivity, and NSW conductivity (optional, not really that important). See my build thread for how to implement these failsafes.

    In your freshly mixed SW do you have a pump in there to agitate it? I might turn on my mixing pump for 5 minutes 2x per day or something...just to keep everything mixed up.

    I have a powerhead that runs for 4 hours when I set a VO to AUTO saying that I just mixed new salt. It also turns on twice a day for 5 minutes no matter what.

    I have heaters in the reservoir, but I only turn those on when I anticipate a need for a manual water change to limit KH precipitation.

    I ran an AWC system for a while but found that my refugium did a much better job at nutrient export. I eventually even turned off my skimmer. You have a CaRx so your major elements are already being replaced. I had to dose the trace elements (particularly iron since the chaeto sucked that right up) but I gladly did that to not have any more water changes.
