MP20 or 40W? (1 Viewer)

[bevoboy]

75G RR mixed reef. LS and about 110 lbs of LR. Currently running koralia's but am thinking about switching to vortech for the controller functions. Question is, do I NEED the MP40 or will the 20 work? I know more flow capacity is always better, but that extra $130 would pay for my ATO. Unless I NEED the 40 then I'm probably going 20.

Little help, please.

Go with the 40, in the long run you wont need to upgrade, if its a little to much you can turn it down a little bit.

Go for the 40!
I have a MP40 in my 120 and really like it. I st up a 57 gallon a few months ago and went with a MP20. Big mistake, even though it is an LPS tank, it just doesn't produce enough flow for me.
