Red Sea reefer sump recommendations

[happysalt]

Hi I’m looking for some advice on the Red Sea reefer sumps. I’m buying the 525xl and want to maybe upgrade the sump to one with a refugiun. I will be running an external auto top off so maybe converting that small glass box could be a posssibility. Anyone have any suggestions for another sump that fits well, has the most water volume, would allow me to use my klir filter roller and maybe a Refugium?

If the 525XL you're buying has the V3 Sump then it comes with a refugium divider.

Oh I did not know that. I'm going to have to remove that small auto top off container to allow for me to fit my filter roller in there. Are the baffles and whatnot hard to remove if I wanted to modify the sump?
