IM Fusion 15 VCA Nozzles?

Mike_Saw_75 · Nov 21, 2023

So I just received my IM Fusion 15 tank (Thanks to BRS and their giveaways this week) and I plan on starting a build thread once I figure out my game plan. I do have a question though about the VCA nozzles available for this tank. They have 3 options on their site and they are listed below. I am wondering what the best option would be for this tank. I do know I will be upgrading to the Mighty Jet 326 to get more GPH.

Option 1: 1/2in Random Flow Generator® Nozzle paired with the 19mm Slip-Fit Drop Adpater.

Option 2: 1/2in Random Flow Generator® Nozzle With Loc-Line

Option 3: Dual 1/4in Random Flow Generator® Nozzles with optional 19mm Slip-Fit Drop adapter.

I am not fond of the IM Spin Stream due to the moving parts.

Hmm.. I don’t have the VCA nozzles on my tank yet, but I plan on getting the third option or the spin stream. I’ll update when I get it!

I don't have the 15, but I imagine it's similar to the 14 peninsula they make. I have the dual 1/4" nozzles on mine. I like that having 2 of them means I can direct flow to different areas, and my corals seem happy enough, but I am not convinced it's giving me better flow than the stock duckbill return... I have to have one of them pointing up towards the surface to get much surface movement at all, while the stock return created movement while pointing horizontally/slightly downward.
On the other hand I'm not running my return pump at full speed so maybe that's my issue! I think it's on 1.5

I run option 3 on Nuvo20 pair with scicce 1.5. I had spin and the concept is good but the moving parts cause it to get stuck with detritus and gunk.

I did end up getting the drop kit along with the 1/4" dual nozzle (Option 3) and ordered from BRS while they were on sale. I also ordered a ton of other stuff for this tank and will work on starting my build thread soon. Thank you for the feedback.

Wow! Did you win a tank from BRS?? If so, congrats!!!

I am tagging along out of interest. I had an IM Nuvo 10 and I had a SpinStream for it. It was loud for sure! Now I have an IM Nuvo 15, and I can't even figure out how to connect the SpinStream to the IM Nuvo 15. None of the adapters that came with the SpinStream seem to connect to the IM Nuvo 15's plumbing. Maybe I'm doing it wrong, or maybe it's because I purchased the SpinStream a few years before the IM Nuvo 15 was available. Maybe now the SpinStream ships with an adapter that fits the IM Nuvo 15.

I'm sorry for going off about the SpinStream, I did see you don't want one, and I don't blame you. I am subbed to see other suggestions because my SpinStream really didn't work for me.

Best of luck with your new IM 15!
