Yes it's a Glass-Holes overflow 700gph. As for placement this was my first drilled tank what do I know-lol.
This being only my second internal skimmer I'm no expert on them. But compared to the previous SCA-301 I was using, this Icecap rocks! Quiet, powerful, very small footprint, a snap to dial in and easily taken apart for complete cleaning.
For the first time in my reefing life I jumped on the stupid hype train with the Gyre. The draw of having 1 power head plus price was key. They sold it well. However after a year I found it definitely was not for my tank.
Today thanks to @mfinn I'm now running 2x Jebao RW4's. Man what a difference! No more dead spots, many options, powerful and night mode. Love these little things and they cost half what the Gyre does, doing twice as much.
On a good note. The algae in the back is now gone. I removed a rock I had in the back corner, my Gramma called home. Was always digging under it. Anyways when the Gramma jumped tank I no longer saw a need for the rock, to the sump it went. Algae no more go figure
