2 tanks 1 filter?

I have a finnex px360, and I want to use it on 2 mini s side by side. It has 1/2" I'd tubing both in and out. Can I put a T on each line and run it to 2 tanks using a step down to 3/8" tubing?

The problem with that is that if one intake gets clogged, anything, it will keep putting 50% of the water in the tank and not pulling 50% back and equal flood. There is no way to really do it that way and get it exactly 50%/50%. Even 0.5% off different of intake vs/outtake and it will flood. What some people do is put the intake in one tank, outtake in the other tank and the make a couple of U pipes to sit between the two tanks that start a siphon on so it keeps the balance between the two tanks. Really though, even that way has limitations because there is no intake in 1 of the tanks and its not pulling in any debris, etc. The other thing is that if a bacteria/virus/etc gets into 1 tank, it will take down the second tank with it. Buy a second filter. lol. Easiest, safest way without risking killing 2 tanks or flooding.

I agree - It is bound to fail or flood.

maybe if you put a water bridge between the two of them that reaches to the bottom, the water would level out between the two of them regardless of whether the intakes were clogged or not.
like this You could make it out of CPVC and it wouldn't need to be clear, throw some mesh or sponge on there if you don't want to let the animals go from one to the other.

what i would do is put them side by side take a pvc or something simalar an make a u but upside down an suck all the air out to equal the pressure between the two tanks so when one water level drops it pulls from the higher one *simple gravity* id use a 1inch pipe to insure it doesnt clog an can keep up with it. then place outlet on one side an intake on other tank should work like a charm for ya . then put a prefilter spong on them if u want shrimp to stay on one side vs other.

as for the pulling debris if it doesnt have enough flow add a lil power head an for the virus, bact, ext ext quarintine your fish befor hand and your done its the same concept as some of the plant tanks at petsmart that use one pump an have several tanks flow to a lower tank.
