Hey Pj. Yes they are. So far they are working well. It takes a little time for them to quiet down. If you listen closely, you can hear them. They definitely need a good amount of flow to work properly. I purchased two of the IM dual nozzle attachments and four of the spinstreams. In order to run all four, it would need a powerful return pump. I opted for 2 smaller pumps to run each side and it is working well.Are those SpinStream nozzles? How do you like them? Any issues? Been thinking about trying them out there is another brand I think.
The rotating flow dynamics makes sense to me. More so than RFG nozzles honestly. I am getting a lot of surface agitation which is nice and they hit so many different spots below too. When those are rotating and the MP10 goes into a higher setting, I see a lot of random movement throughout the tank. I still have at least one more wavemaker to add to the back for detritus movement.
I haven't added any corals yet though, so we shall see how good they'll do to help with that. They are a little unsightly for some folks, but I'm trying to learn to ignore them. I figure eventually, when all the coral are in the there, it will be easy to ignore.
