Two Nero 3's not enough for Reefer 250?

[bearman88]

Hello - I recently changed from a single Icecap 3K gyre, to 2x Nero 3's for my Reefer 250. I run these on 95% power, and it seems to be OK for about 80% of the tank. But I am getting dead spots with cyano and detrius, and starting to think I should have gone with Nero 5's. Specifically in the bottom back corners.

I have a fairly minimalistic rockscape, so I didn't think the flow would be blocked too much. Any thoughts here? Each Nero 3 is 2000 GPH max.

Why not run all three… the gyre and the 2xNeros?

Hmm not a bad idea. I could run the gyre vertically in a corner and create an outer loop of flow. I'll give it a shot! Thx
