smallest size for SW mini reef tank? Question

  1. Betafish305ca Member Member


    How small can a SW tank be if you want to use it for a mini reef.... kind of like those nanocube reef tanks, but maybe smaller (and possibly cheaper) if possible???

    Also, on a 2nd site note.... if the tube is tall enough, is it possible to have a chiller at the bottom of the tank, and a heater at the top part of the tank? Or would the different from the top to the bottom (or reverse) kill a fish if it made the transition?

    the smallest ive ever seen that could be "done" are PICO's. 1g up to 5 i think

    does overstocking apply to reef tanks?

    Absolutely. Even more so than for FW tanks.

    Eventually I would like to start a 5.5 gallon reef tank. I think that would be a perfect size for a "small" reef.

    5.5 gallons sounds good.... does that sound like a good size??
  7. harpua2002 Fishlore VIP Member

    Sure, but don't expect it to be cheap. I started with a 2.5 gallon and probably had $250 into the setup by the time I upgraded it to a 5.5 gallon. You'll need reef lighting if you want to keep corals, and the corals themselves can be pretty expensive. Also, keep in mind that small reef tanks need a lot of attention. I had to top mine off with FW twice a day because of evaporation (evap causes a rise in salinity). And when things go wrong in a smaller tank, they go wrong quickly and you have to be prepared to deal with problems before your tank crashes.

    I have a 5.5 gallon setup and its very nice. I think nano tanks are fun to have if a larger tank is out of the question.

    ya, i know that the smaller the setup, the harder it is.... but i'm an apartment kid of the next few years, so i can't really go big... would this setup work (roughly??)

    Depends entirely on what lighting you have and what you want to keep.

  11. Betafish305ca Member Member

    any suggestions as to what you strive best in that sort of set up???:;fr

    thanks for the advice.... could i mount lights to the outside of the tank, on the metal supports i have around it? cause its a deep and narrow tank with an iron support i already have... think that might work??

    I don't understand from your pic what the dimensions of your tank are. Could you measure and post the dimensions? That would really help to think about what lighting would work for you.

    Okay, oops.... sorry, its;
    L 7.5 inches, W 7.5 inches, H 18 inches

    Are zoanthids and mushroom coral? i'm not sure

    That's a really odd size... sounds like aquascaping and cleaning would be very difficult. With all the sales going on right now, I would suggest picking up a standard 5.5 gallon or 10 gallon tank.
  17. Betafish305ca Member Member

    oh, u think so? I was trying to do this size because its something that i have around the house....

    Type of what? The standard 5.5s and 10s are all the same dimensions. Just pick up a cheap one.
