Peninsula Tank Build – Circulation

This is Part #15 in a series of blog posts about my 225 gallon peninsula tank build.

Peninsula reef tanks can present challenges when it comes to providing sufficient circulation for corals, especially SPS. It can be unsightly to have pumps on a viewing panel so many folks place them on the end panel.

With my six foot long tank I have to push a lot of water so my plan was to really beef up circulation. I started with four Ecotech MP40’s. Each pump can push 5,000 GPH of water. I put two near the bottom of the tank and the other two near the top. They were placed 3-4” from the corners of the tank.

Experimenting With Different Modes

I tried various modes, starting with the Short Pulse mode. Over the years I have always used this mode on my Ecotech pumps since it creates a nice surge. But the Short Pulse mode could not deliver the amount of flow I was seeking across the six foot long tank.

I also tried the Gyre and Reef Crest modes but again they did not move enough water. To solve the problem I decided to swap out the two MP40’s near the top with two Ecotech MP60’s. Each pump is rated for 9,000 GPH.

And the Winner Is?

I played around a lot with the different modes and settled on the Gyre mode. All four pumps were set at 100% for this mode.

I felt the Gyre mode pushed the most water and I really liked the clockwise and counterclockwise flow patterns. I thought it would be my best bet to keep detritus suspended and deliver nutrients to my corals.

Future Considerations

Will I need to break down and add some pumps at the other end of the tank when my corals start growing? I really want to avoid this but it might be possible to hide the power cords with some cord covers on the top of my stand.

One final thing to note about circulation are my two Red Dragon 100W return pumps. Each pump is rated for 2,400 GPH.

They are set to only 50 watts since a higher speed would drop the water level in the sump too low. However, 50 watts per pump still adds a lot of additional flow to the tank.
