For me, even with the sicce pump it doesn’t have enough flow to actually push the rfg to make it do what it’s supposed to. They’re rated for 160 gph plus. The sicce is 158 gph. With the single rfg (I’m not using a vca, but rather the original rfg) it actually looks like there is a wavemaker in the tank. Excellent random flow through the tank.
If you plan on running SPS then the prime is definitely for you. I prefer the kessil because I’m mostly lps and some softies. The only sps I have are leptos and some people don’t consider them sps but either way they prefer low light. Still enough light to keep my RFAs happy too. I never have algae problems, and haven’t since I set it up with dry rock and sand. Barely even a diatom bloom.
Just make sure you get the 158 gph sicce if you go with sicce. I bought a mighty jet for my fusion 15 and sized it up to see if I could run one on the Deskmate, and I know there’s a few people who have but the clearance is extremely tight, and I just wasn’t willing to go that route. Also anything more than the sicce and you’ll have to cut the overflow weir out.
Not trying to tell you what to do, just what has worked well for me. I’m no Lou Schiavo but I have found a lot of success in my Deskmate. Nonetheless consider a light shade for your prime, they actually make a difference and clean up the light the leds put out. I would suggest running the penny wise schedule (whichever one you go with, I run the dead lights) on a very long acclimation starting st a low percentage just to avoid algae as much as possible. It’s hard to get enough CUC in a tank this small that can keep up with much of a bloom.
