I recently purchased the cobalt C-vur 40 gallon tank. I am looking for suggestions for a good wave maker. Also is a Gyre Pump a lot better then a powerhead.
Gyres are better at creating a rotating flow around the tank, which is what some reefers prefer. Many times a single powerhead wont be enough because its very directional flow and it misses a bunch of spots in the tank and you wont really have that issue with a gyre. That problem can be countered with multiple powerheads on opposing sides alternating flow throughout the day or so. "good" wavemaker is subjective in my opinion. I have Maxspect and Icecap gyres now but have also used Jebao wavemakers and gyre in the past, I have enjoyed them all. Your budget will most likely dictate what you can buy right now.
