I should mention the primary reason for the thought of switching is I never like the flow pattern the Vortech pump can generate. Two MP40 at an end is not enough to push water all the way across 6ft tank. Not the it has not enough raw power, but it's the current is so turbulent that it disperse around 4~5 ft mark. I think a real gyre pump will do a lot better at pushing the current to the very end.
Agreed. In hindsight I would’ve gone MP60s for my 180 just for the sheer fact MP40s barely, and I mean barely, stay attached on 3/4” glass.
With 4x MP40s flow has never been a huge issue though. I run mine opposing each other on reef crest/constant as described in the coral labs documentation.
Just recently staggered them so that I have a “top” and “bottom” pump on both sides with bottom and top opposing one another. Really happy with the random flow created.
I tried the early iterations of the Gyre pumps and found them very unreliable and required much more cleaning.
Are your connectivity issues with Mobius?
