Canister filter on 2 nanos

First off, I'm a complete newb.

Second, is it possible to run both 5.5 and 2.5 gallon nano tanks on one Rapid's Mini Canister Filter? And if so, how might I go about doing this?

I've already got the Rapid's set up on my 5.5g nano, and the 2.5 nano is right beside it.

Thanks in advance!

Dylan

It would involve some piping and check valves to control the flow... that being said it depends on what you have and how much suction the filter would have...the piping would basically be like a t-valve, one connecting to the intake and another t valve connecting to the return, however the return would have to have a check valve of some sort to check the flow on the smaller tank...

P.S. why not just use small sponge filters or box filters?

Sheer Madness!!!

Well, so far I haven't been able to find any small filters around here that I liked to I thought I might be able to do something with the Rapid's Mini Canister Filter since I already had it. Will probably get a small sponge or box filter though if I can't make the Rapid's work effectively on both. Thanks for the replies though.

The only way to use one canister on two tanks is to have one tank overflow into the other. Trying to split the intake and outlet in two tanks will drain one tank and overflow the other, no matter how careful you are adjusting ball valves to balance the flow.

It could be done, using float valves to stop overflow, but it would be a lot of work for just those 2 small tanks.

If its even possible to make this work properly and efficiantly you would probably have to spend more $$ in parts then what you have invested in the canister. I just bought a mini internal filter for my nano thats rated for a 10g for 10 bucks at my LFS. great water circulation and clearity and its VERY small and compact.

My suggestion would be to keep the canister on the 5.5 and go with a mini internal for the 2.5 or....

A couple months ago i removed the pump from one of those decorative waterfalls thingies. It was gonna be trashed anyway. I took the pump, some siphon tubing, a tupperware container and some hot glue and made a mini canister filter that works like a charm. Im still using it on my 2.5 betta tank.

P.S. If you decide to try this at home, make sure you test the tupperware container FIRST! Put some water in it hold it upsidedown and give it a slight squeeze. if no water comes out your good to go.

Have been toying with this idea for 2-3 DoAqua! cubes that would be arranged side by side (used as a betta barracks of sorts). Would allow you to share a filter and a heater in addition to allowing a larger volume of water to buffer against chemistry changes. Anyone try this?

If so, what's a good source of clear overflows to connect one tank to the other?
