I love gyres and use them in my main system, sump frag tank and also in a separate frag tank.
They produce a wide, strong current and when setup correctly can also form the gyre effect, which amplifies the flow even further.
And while I think it’s one of the best flows a wave maker can produce, you should also be aware their big drawback compared to regular wave makers: they’re a maintenance nightmare.
Basically, they simply clog rather quickly compared to other form factors, and they significantly longer to clean.
If you decide to go with them, prepare yourself to clean them once every 1 to 2 months (in an established tank).
For me, I balance them together with many other pumps with a regular form factor so ai only really have 4 to maintain (out of 11), and I find their benefits to out compete their drawback.
