I'm looking to pick up a larger acrylic tank (about 125-135 gallons) for a planted discus tank and many of the used tanks have been used to keep reefs and have overflow chambers drilled for sumps. Can I connect a tube from the sump hole directly into a canister filter like the XP3 or XP4, or will the pressure be too great? I can use a sump tube that is narrower diameter to reduce the flow a bit.

There should be no reason why not, because the water will only flow over the overflow as quick as you pump it back in to the tank so you will never have a problem with pressure. Your only concern will be as you know with you marine tanks is evaporation, which will slowly empty your canister filter and damage it.

Why not just go with a full sump system? That is what I use.

Good Luck

I've read that full sump systems with wet/dry filters remove a lot of CO2. And simplicity - I've had great success with good canister filters, like the XP3. Great flow, lots of media room.

What would be the advantage of the full sump system?

The best thing about a sump system is you have no hardware in your tank, so all the heaters, bubble counters, etc are all in the sump and of course a better and easier filter to work on. This is a personal opinion and I am sure there are people that would disagree.

I have heard that you loose some CO2 with a sump, I have a seachem 1000 reactor and I have been very very happy.

Good Luck
