Hey gang, anyone found a good solution to this? Running something external with my hydros as a no-brainer, but I really would like to keep everything in the cabinet if possible. There definitely is no room on the left side as that's for my controller board is. I have a 3 gallon cereal box that I was using on my previous tank that is a slightly bigger footprint than the small glass reservoir that comes with the reefer. However that cereal box is precariously perched on top of the filter sock overflow as the stock box would sit. Besides commercial solutions I am also interested in what anyone has modified or devised themselves. Thanks!
Don’t know if this would maybe fit in right side, not famiakr with the 200xl.
