    Auto top off pump?

    Hi all,

    This is one of the last pieces I'm missing, can anyone suggest a pump for an auto top off? I need a tiny water pump or powerhead to go into a 2.5G reservoir.

    Cheers!

    Maxi-jet's work great! Dependable and cheap.
    And they don't mind being cycled too much.
    Of course, as long as you're not pushing the water to high.

    Exactly.
    Maxi-jets are great in this application. I've been using one for my top-off for well over 2 years of constantly going on and off... I had to use a Maxi-jet 1200 however since I'm pushing the water through a tiny 1/4" hose.

    How do you reduce to 1/4"?

    Doesn't that cause a bit of pressure? How did you secure the line into your tank / sump?

    Cheers!

    I use a peristaltic pump. Works great! Does kalk too.

    I wish, a dosing pump isn't in the budget this time around lol. It's definately on the wish list though.

    Cheers!

    I'm Using a Maxi-Jet also.. It's pushing about 3' of head so the 400 wouldn't cut it. The 600 was questionable. To be safe I went with a 1200.

    So are you pumping fresh water back into your display or sump?

    I was planning on the sump & there might be a couple of feet of hose, but it's going to be more or less level. Maybe 2" of head lol.

    Cheers!

    Krugar,

    And, be careful not to set up a syphon from the top up water to the sump.

    You could set it up so that the pump cycles on and off and the water keeps flowing. You can:

    1) put a tee and a check vavle at the high point on the line.
    2) make sure the output of the top up line is higher than the high water mark in the top up container. (this way it cannot syphon)
