Running a closed loop to plumb remote canister filters?

[BadGaskets]

I'm considering running a closed loop on an undrilled, CO2 injected 120g freshwater tank (basic PVC) so that I can put canister filters in an external utility closet. There's about 30 feet distance to the closet. This would get the filters entirely out of the house and make them much easier to service.

The canister filters won't have the power to push much water that far. I have a big Jebao pump that I can plumb inline with some 1.5" PVC that will basically serve as a sealed water access point for the canisters. I will need to use some barbed fittings to connect the canisters to the PVC.

My thoughts are that this will work as long as I have the canister suction side on the upstream side of the closet loop.

Has anyone done anything else like this, to get remote filtration without having to use a hob overflow or drill?

As a side note, the reason I don't want an HOB overflow is mainly because of the CO2 injection. Ive tried that before and it definitely offgassed the CO2 despite my efforts to seal everything off.

Unclear, can sketch?

larger diameter (PVC) inlet/drain lines will be good to reduce pressure needs for flow rates, but beware that too big & there's not enough flow to shift muck, and it'll build-up. Also snails etc... can start living in there, & dead shells can then become a thing. Also beware of heights & levels - Jebao specs say to not submerge more than 5', which isn't much once you start running pipes through different rooms as head rather than depth.

Most of my tanks run a bit of distance to a canister. My canisters are (mostly) home-made from various buckets & drums & home-made O'rings... not sure i'd recommend if you'v got access to the-real-thing; however, I get massive can/media volumes & my plumbing is all standard, so cheaper & larger pipes, unions & valves & no barb fittings.

IME push vs pull (suction vs pressure?) isn't much of an issue in a sealed can system but for where the muck and/or detritivorous fauna might be, IE before or after the filter, and priming. Cleaning also, maybe. And leaks.

The Jabao is Ok to not be submerged? I've had mixed results over years & the specs are unclear. I seem to be mostly/only using Jabaos these days, but all are submerged either in the tank or sealed inside the canister. I think I'd prefer external, but I'm getting used to the silence

I think 1.5" pvc will be a pit much pressure for 30' of travel. I would probably stick with 1"

But I have seen this concept done multiple times. and it is super simple. Canister filters are just media beds and as long as water is moving through them they do their job. You just have to have a big pump and trust your PVC skills enough to have them pressurized. I also dont reccomend puting the canister on a lower floor than the tank as they are only rated for so much pressure.

Also with the jebao pump IDK if you will rn into overheating. I would find a tub or 10 gal tank to submerge it in while you run your plumbing externally so you dont run the risk of overheating, or maybe find a pump rated for this kind of distance and water pressure

You could also inject CO2 into the return line for better mixing

Just some things to noodle on, good luck with the endeavor!

Isn't this common for outdoor ponds? I believe there often is piping to a shed where the filtering takes place, I'd look more into their implementations and concerns.

I run my sump through a canister filter before the water returns back to the tank. I’m not 100% sure if that’s what you are trying to do… but the canister is on the other side of the room. And I run my return pump anywhere from 40-60% depending on desired flow rate.
