    Auto and Constant Water Changes

    stenner.jpg

    So I got my stenner pump installed today, its plumbed into a 100 gallon storage tank with a mixing pump and hooked up to my apex. So now I can either just push a button on my phone to do a water change, or I can have the apex change it constantly. Im wondering if anyone else is doing this and is so, how is it working for you?

    Thanks Cody for all your help getting it setup!

    No problem, Gregg. Like I said tonight, "could you imagine running your reef tank without an auto top off system?" It would be an unnecesarry and unsuccessful pain in the butt if you were trying to keep most corals. The difference is that water changes dont just effect the salinity. They effect the export of nitrates and phosphates, while importing your minerals that the tank needs, yet on a daily and consistent basis. You're talking about a system that exports the bad and imports the good. Folks spend how much on skimmers, yet they don't know to spend the money on a tool that can have a much bigger impact on their tanks. I'll be putting together a package soon for folks to automate their water changes, just the same as their auto top off systems. Your set up definitely takes it to a new level of clean though.

    I had all the parts for it but never got to it as I told myself, if I can't lift a 5gal bucket of water anymore I shouldn't be in this hobby.
    The trick is though that all tubing's need to be the same length and have similar turns, as to you have always fluid flow resistance and over time that will throw off the amount coming in and going out.

    That's not necessary. You'll never reach a 1000% equal exchange of export and import of water. Your goal is to get it as close as possible, which greggs and my pump do a damn good job of. It's a peristaltic pump with two heads on the same axle. The reason I say that I doesn't have to be exact it because of personal experiments.

    In my experience, my salinity will change from 1.026 to 1.025 in about 4-6 weeks, assuming that my fresh saltwater is at 1.026. Is that the fault of the pump or the skimmer? Maybe taking out water for bagging up corals? Even without the auto water change system, a tank can fluctuate as much on a similar time frame. The only difference is that I can go 3-4 weeks without making saltwater, have daily water changes, and much more stable tank parameters. Whenever the salinity in your tank hits 1.025, you boost the salinity in your fresh salt water storage to 1.030 and you're fine, assuming you do a maximum of 3% water changes daily. It will slowly move the parameters back in a stable and safe manor.

    I have an air stone in my holding tank that comes on when the water change pump turns on. That's probably overkill, but I just want to make sure the water isn't stagnant for a long period of time. Again, probably not necessary, but it makes me feel better haha

    Couple of times a day should be ample.

    How often do you add salt and the difficulty part is how do you get your salinity right while the auto water change is "ON".

    Sorry to bring up this old thread but I have a question.
    Are you running the pump once a day for a set time or do you have it come on several times during the day?

    the stir pump come on every 2 hrs for 15 mins... the water change pump comes on for 30mins once a day.. that equals about 3% water change per day.
