I’m looking at trading my Red Sea 425 xl for a 625 xl, however he doesn’t have the original sump and wants to keep his aftermarket one. Would my 425xl sump be comparable with the volume of the 625xxl? Any foreseeable issues? Ty!

How many gallons is the 425 sump. I have a 625 as well and the sump is 32 gallons. So the only issue I would think of would be flow maybe from the return? I’m new to this but I would think that would affect it somehow but don’t quote me on it?

A few points to consider
1) I'm assuming with bigger tank you will get more fish. Would you need bigger equipments to handle the bigger bioload? If so, can your smaller sump fit the bigger equipment?
2) do you use your sump as a refugium? If so, it will be less effective because it will be harder to compete against the algae in the DT bc now relatively speaking it will have a smaller surface area for light and photosynthesis.
3) do you have an ATO? If not you will have a more frequent top off cadence bc larger tank = more evaporation so the water level in your current return chamber will drop faster.
