Calc Reactor help

[harrylikesfish]

So I’m planning a 180 gallon reef (40 gallon sump) and I need help to get chose between the reef octopus cr200 and the cr140. The cr140 seems too small and the cr200 seems too big and I’m wondering if there’s harm to getting an oversized calcium reactor?

Depends on your current demand and what your future demands will be.

I would rather oversize vs undersize.

Same here, a smaller reactor will need to be filled more often
