I'm planning on getting new circulation pumps for the 120g tall 4x2x2 roughly. Would it be better to dk a gyres or one gyre or 2 wp40s. What would you do?
I have a 90 and had 2 mp40s, one on each end and about a month ago switched to 2 gyrees and the flow is amazing l. Definitely won't go back to propeller style pumps
