So I picked up a used 90 that came with a Bubble Magus A5 Curve. Planning a mixed reef medium load....will the A5 be enough or should I just sell it and buy a bigger skimmer?
Thank you
Since it came with it I would just run it for a while and see how you like it. I have no direct experience with that skimmer but it seems reasonably sized for what you have planned. You can always upgrade in the future if your stocking levels get heavy and you feel like you need more export.
