One filter, two tanks... possible?

[Snakehuntr_007]

I'm trying to use a canister filter for both my 55 gal and 75 gal. Has anyone ever attempted this before? I'm trying to save money.

I would love to know how you propose to do this!



sorry, the answer is no, not possible with a canister filter unless both tanks top rims are at equal heights and they are drilled and connected via bulkheads and PVC pipe.

or ..... if you could somehow get two inlets and outlets and make a DIY spliter to get one hoes to turn into two and i think it would work assuming u have a big enough filter to handle bother tanks what kid of filter are you looking at getting ?

no, what if it drew faster from one tank and returned faster to another === water on floor!

I would just buy two filters. The alternative is to buy a large sump, two overflows, and two return pumps. That is the only way to have one "filter" and two tanks.

Water exits the filter and goes to first tank,
It overflows into 2nd tank and then back into filter.

So to use one filter for two different tanks all you need to do is have the 2nd tank slightly lower than the first....somehow...
People do this all the time when they connect different sump tanks in line.

Yeah, you are right, but someone that is too cheap to buy 2 filters likely cannot drill a tank to achieve this. It cannot be done with a overflow box, if it fails, water will still be coming in.

Second tank is never filtered properly.

You can use a water bridge to connect 2 or more tanks if you dont want to drill them.

a single sump would be your cheapest and safest solution .Dual outputs with gag valves so you can control the flow to each tank
