Vortech Flow

[BriansBrain]

My current tank is a 60”x20”x21” mixed reef running for 1 year. Looking for some input/ideas on a variation of modes to run and mounting for MP40’s. I feel like Ecotech doesn’t really give you the keys, unless there is info I haven’t seen, about proper set up and function of the pump other than a short write up of the modes.

I’m running 2 MP40’s on opposite sides currently running all reef crest from 60-90%. One master one slave pump running antisync. I did not unfortunately leave enough room against the wall to mount them on the back glass... rookie mistake. I also have an internal overflow on the back middle, so it impedes direct flow across the back.

My issue is with the pumps pointing at each other, it creates a strong gyre in the middle. On each side there is good sporadic chaotic flow up top for acros, but towards the bottom 1/3 it is strong one direction back towards the pump. My meatball lps do not enjoy that lol. I’m trying the antisync thinking it would move that gyre around the tank but it doesn’t really. The pump are about 5-6” from the surface. If I put them lower it seems to not do as good a job with surface agitation.

Acros and sps towards the top and middle, lps/zoas at the middle to bottom. A variety of corals in a mixed reef is difficult to keep them all happy.

Have you tried running them anti sync, both from the same side like a peninsula tank? I would try 1 high and 1 low and see how that works. Another option would be to add a gyre or 2 on the back and see if that helps.

They are currently in anti sync but not on the same side. I have not tried them on the same side because I have an internal overflow from top to bottom about 12”long 4” wide. I guess I won’t know until I tried though!

On my 8’ I run Tidal swell anti sync with 2 MP60’s facing each other but off set just a bit. I also run 4 MP40’s on the back, I like tidal swell better than reef crest with them facing each other on anti sync.

You could also move them towards the front more and run a gyre or Nero5’s will fit on the back wall

What mode do you use to get that gentle LPS sway back and forth with 2 vortechs, without a wave if possible?

Their website has a model where you put in your tank dimensions and they give up a recommended flow rate. It will be lower than you think.

Yea it’s definitely lower. I entered my info and it recommends only 1 MP40. I tried running 1 MP40 on 100% and it barely made water move on the opposite side. Not sure I buy that recommendation

I alternate my 2 Mp40 with 1 in constant the other on reef crest. Seems to work fine...
