sps and flow

[Reef Pilot]

I have 2 WP40's and 2 Coralife DC5800 Wavemaker pumps running in my 100g SPS tank, as well as my return pump flow. That makes for over 6000 gph flow in the tank. All the wavemaker pumps run on turbulence and random flow during the day, so that really mixes up the flow patterns. Then at night the light sensors direct the controllers to dial down the flow (but not shut off), so the corals and fish all get a rest.
