Xf250 sps setting

[An ngo]

i have one gyre xf250 for my 80 gal. Dimension is 36”x24”x24”. I plan for sps. Right now running 20% and 10% backward gyre mode but sand keep lossing at the corner. Asking for the best setting for xf 250. My gyre put on the left top of the tank

The Oceanic Gyre Cycle works well for me but my tank is 72” long and I have two xf250’s, one on each end. You can adjust the angle of the fan covers to blow more upward if sand is blowing around. You can then play with the power settings within the OGC to what suits your tank best. SPSLike lots of flow.

Yeah but the flow hit the glass and bounce back to the bottome of the tank and flow off sand. I try to play with that couple days but sand still fly off at the corner

Have you tried lowering the gyre in the tank and pointing the flow upward? This may create enough drag to slow the flow by the time it hits the opposite side of the tank that it doesn’t move the sand.
