Would having 2 canister filters running in this sequence cause current in the bridge? Seems to me in a regular setup with 2 or 4 HOBs the water in the tube would be stagnant.
Canister A - spraybar in tank A and intake in tank B
Canister B - spraybar in tank B and intake in tank A
This way water is always being pulled through the bridge going from 1 tank to the other.
No, there would not be any current in the bridge. The flow in/out of each tank through the canisters would neutralize the flow in the bridge.
IMO, the best way is to add another filter, like this set-up-
Canister 1- spraybar and intake in tank A.
Canister 2- spraybar and intake in tank B.
Canister 3- spraybar in tank A, intake in tank B.
It's best to have atleast 1 dedicated filter for each tank and 1 filter for each water-bridge. If you ever need to shutdown the water-bridge, you'll understand why. (Actually, you can get flow in a multitude of bridges with just 1 canister).
Here is my 4 tank set-up-
Canister 1 Filstar XP1 - spraybar and intake in tank A.
Canister 2 Filstar XP3- spraybar and intake in tank A.
Canister 3 Filstar XP2- spraybar and intake in tank B.
Canister 4 Filstar XP2- spraybar and intake in tank B.
Canister 5 Filstar XP2- spraybar and intake in tank C
Canister 6 Filstar XP2- spraybar and intake in tank D.
Canister 7 Filstar XP3- spraybar and intake in tank D.
Canister 8 Eheim 2026- spraybar in tank A, intake in tank C.
Canister 9 Eheim 2026- spraybar in tank D, intake in tank C.
Tank A is a very low light 90g river tank.
Tank B is a low-light floating plant 95g tank.
Tank C is a med-light fully planted 85g tank.
Tank D is a high-light fully planted 190g tank.
My CO2 reactor is connected to the output to a XP3 canister on the 190g tank.
My UV Sterilzer is connected to the output of the Eheim canister going to the 90g river tank.
I will add another UV sterilizer to the other Eheim canister in the near future.
Another note (Warning)-
Disease control in a multi-tank set-up like mine is very difficult.
Sick fish can go unnoticed for weeks, maybe months. They can move from tank to tank and you might not ever see them until it's too late.
Unfortunately, I have 3 Quarantine tanks running right now, treating sick fish.
