Does anyone throttle back their Vortechs?

[JG1]

I have two MP40w's on a 48x24x20 running on NTM.

The flow is pretty crazy at 100%. Was debating throttling back to 75% but don't know if that's sacrilege with these pumps....lol

I was running RC for a little while but I think circulation and randomness is better with NTM.

Reason I say is I don't have great polyp ext during the day yet, but at night everything is extended and the polyps look like they're being blown violently back and fourth. Maybe they love it, I dunno.

I don't have much LPS but I have a nice green/purple frogspawn frag that I can't make happy because of the flow. Just added a pink boobies chalice and at night it's sweepers were being blown everywhere.

i have one on my 4' 120, with sps and lps, its def not enough flow, a second one is in the future. seeing the flow of one, i think two dialed down a bit would be perfect, plus hopfully a little more quiet.

I have two MP40's on my 120 and keep them at full power. I tried turning them down a bit (~70%) for a while but started noticing some of my acros losing tissue at the base so turned them back up to 100%. The tissue loss stopped, so I will keep at 100% permanently from now on. Just my anecdotal experience though so take for what is worth.

i had 4 mp 40 on my tank and had them running at 75% and didnt see an issue.. i then put them on 100% and had a small sand storm so dialed them back down.. it depends on the setting you have it on as well ... i have mind on reefcrest and the randomness is great..

I have one mp40 on 90% in lagoon mode. That's accompanied with two tunze 6045 on a 4ft 90gal. Would love to add one more mp40 in the future.

I just set the NTM @ 75%.

It doesn't look like such a storm in the tank now.

is the ntm light purple in colour on the vortech controller?

Hmm, I'm not sure. I change the modes through my Apex controller. I haven't touched or looked at the vortech controller since I set the tank up.

I don't have any SPS nor other type of hard corals, but I can tell you that you'll never have more flow in your tank than in the ocean. It's just like lights. You simply can't bit the sun's power with artificial lights.

I have 2 mp40's on my 65g running at 70%

@JG1

My tank has the same dimensions and my 2 MP40w's run at 65-75%. I don't have enormous amounts of rock and my SPS are still pretty young. This has been the best flow for me considering my tank's current level of maturity. I imagine that once my acros are no longer frags but branching colonies, I'll have to bump up my pumps to 100%.

what mode?

 

[silentscream]

Reefcrest. I don't have the new ES controllers, otherwise I hear good things about "nutrient export" mode

edit: reefcrest in anti-sync

I run my mp40 about 60% and the mp10 about 80%. Anti-sync reef crest usually in a 37 gallon SPS tank.

Both of the mp40 on 90% in RC mode.

I have two MP40's in my 4' 120 and run them on constant speed 100% with two maxi mod'ed power heads in addition to that.

I'd like to find a couple MP20's I can put in too.


It takes weeks & very careful positioning but none of my corals get blasted, the flow is random and I get very little to no detritus on the bare bottom, saves me some time with the turkey baster.

Jeez, must be a hurricane in your tank!

Do you have ANY lps?

 

[Jabrams]

I have an mp10 on full blast on reef crest setting.
14g bc sps
