75G tank with SPS one MP40 enough?

[Billyreef-ita]

Hi everybody,
I’m upgrading to a 75G and I will be moving soon my corals to the new tank. I have a mixed reed with a predominance of SPS.

My question is: would a single vortek MP40 be fine?

Two MP40s are out of budget for me, that’s why I was thinking about one only. I went on the EcoTech flow simulator and it seems that it might be ok.

What do you think? Is anyone experiencing this? Thanks

See if you can get one or both used?

My SPS tank is 85g with a single Mp40 and 2 Jebao SLW20's. I need another Mp40 as currently I'm forced to run the single Mp40 too high which gives a rather unnatural flow.

Depending on your scape, you way also struggle with some dead spots as well

I used 2 mp40 when my 75g was a sps mixed reef.

I run a lps reef now and swapped a mp10 and it’s not comparable. The side with the mp40 has great flow. The mp10 side just can’t replicate it. The flow is much more narrow compared to the 40, along with the gyre effect

a single mp40 can cover 50-75% of that tank. You’ll need something else. I got all my mp’s used off a forum…8-10 years ago. Used in good shape is a good investment
