    14' head, low volume pump needed

    OKay,
    have a 90G reef on main floor.
    Heres the situation. R/O unit is in the basement and so will the holding tanks be for water changes. Tank if 14' above and I need an efficient way of pumping the water up there without spending large dough.
    - Sump/refug is in the cabinet under the aquarium.
    - I need to be able to pump mixed salt water for changes from basement because it's easier to make a mess down there.
    - have some way of topping off the tank
    - have way to allow R/O unit to fill bucket in basement and use that to run an auto top-off unit so holidays are possible ;o)

    so how many pumps do I need? they don't have to be fast, just pump high.
    if I run an auto top off unit does it have to be close to the tank?

    Yup your looking at several hundred dollars for a pump that would do that, and the same would go for an auto top off, i don't know how you'd do an auto top off to a resevoir thats 14ft below, because your floatwitch would have to run 14' on an extension cord to a resevoir to turn on a pump, then if you did have a pump strong enough it would probably dump a whole bunch of water in the tank at once, and gravity could pull much more water then you wanted into the tank if there was a hook in the piping to top it off,

    Well, the top up could be based on a a presurized tank and use a solenoid at the sump to control flow. It might be tricky, but still possible, to presurize a tank well enough to get the water up 14' (and maintain "reef safe"). For top ups you won't need a lot of flow, but, most small pumps won't touch 14' of head. Might be easier to haul RO/DI water to a tank local top up tank.

    I dunno cres, i've never ever heard about some one ever attempting something like that with 14' of piping + to go through, highly unlikely that someone would pressurize a tank that far up JMO

    Ummm, anyone with a well ?

    Only need about 25-30 PSI to service a top up system.

    I'm not saying I'd advise it, but, it is an option. The water change would be more tricky.

    I don't mean any disrespect by the way i just think that it would be next to impossible to do that, i really don't see how that could work feasibly

    Well, a small pressure water pump into a sealed container with a float valve or float switch with solenoid at the other end.

    A water tank with an air pump to presurize the tank (and cycle on again as the water - and air pressure - gets lower). Fill the tank, close the lid, turn on the air pump.

    I would still advise (even if only while away) getting a 5-20 reservoir to put by the tank and some form of top up system there. Could be a simple float vavle and gravity feed from the reservoir.

    You say in your post you would need 25-30 psi though, thats a huge amount when your talking about dealing with 14ft+ of piping
