So minor update to the setup....
I recently got sick of trying to clean the algae around the MP40 headphones on my DT. So I decided I'd put them on the back glass. looks way better but now I'm missing a bit of the cross cutting flow... so I bought some Neptune WAV pumps as those can be angled; I figure I'd also put them on the back glass and angle them to have some current bounce off the front or side walls etc.
Turns out the WAVs are too strong for this application... even at 1% my euphyllia looked like they were going to get shredded; even with the MP40s off the WAVs alone were too much (on back glasss). They just didn't work well for this situation. So, I decided I'd put the WAVs in the frag tank & steal the MP40s from there and use those in my DT
The frag tank currently has 2 MP40s (left & right) and 2 Red Sea gyres on the bottom, back. The Red Seas only turn on for 5 minutes an hour and their sole purpose is to blow the gunk off the floor, into the column and, hopefully, through the mechanical filtration.
So now the 2 WAVs are the only 2 pumps powering this tank and they're doing well. They're on the sides but all the way in the back & at the bottom. I angled them slightly as well to get a nice turbulence. This way I get some nice flow and they help keeping stuff off the bottom of the tank.
With a 4ft width the WAVs work fine and I can turn them up without worrying about a torch getting a hair cut. However - they were just too strong on my DT's back glass no matter how I tried to angle them.
TL;DR replaced 2 MP40's and 2 Gyres with 2 WAVs. No not claiming these are better, can do double the work etc... but with my setup etc it's working fine and allows me to snatch the Vortech off the frag tank and repurpose them in the DT
