Reduced flow?

Waters · May 28, 2021

So my algae eating fish are not living up to their pay grade, mainly due to them getting blown around when trying to pick at sections of rock near the powerheads. I plan on reducing flow for 3-6 hours during the day to allow the fish time to graze everywhere (they are at their best when I have the flow shut off and am doing tank maintenance). The flow will be back to normal the rest of the day/night. Will anything negative come from this with the flow sensitive acros?

My powerheads ramp down during the evening when I am typically around my tank. LPS and the fish seem to like it.

No negative effects that I have noticed. I ramp up at night.

I do not see an issue with this. My tank has about 4 hours of lower flow on my sps at about 3-7pm. I have my wave maker program set to kind of simulate tides in relation to flow. High tide means a little less flow at its peak, since the water is higher above, so to speak. Tide change is when things get fast. Have a few of those programmed in during the day, as well. Fish seem to like it, corals do not care and grow just fine.

I worked my tank into it by doing an hour or low flow added in and then kept increasing the time to where it is now. Don’t get me wrong, they still get flow, just not the crazy random fast flow that is there most of the day. Basically they get lps flow for a few hours and then back to sps flow later.
