In my opinion, a slow rate of water flow is better, the same holding true with a protein skimmer. You want the water to move at a slow pace to allow the water to be cleaned so to speak(allow the equipment to be able to do what it is intended to do to help maintain pristine water quality) for example, many people keep refugiums for numerous reasons, however, mostly for growing Caulerpa(macroalgae etc.) to help keep microalgae under control, or to use as an effective means of increasing surface area for bacteria to grow and by having sediment/substrate and live rock per say, the benefit of this is great, the greatest being that of DENITRIFICATION-bacteria removal of nitrates in the paleagic areas(water column) of your tank.
Ok that being said, by slowing down the water flow, you are able to allow more time for the beneficial bacteria etc. to do its thing to better your water(quantity is a disadvantage in this case).
Same holds true with a skimmer with a pump that is too strong for the particular skimmer. If the water is being sucked in and pumped right back out too quickly, the microbubbles are not able to remove detritus efficient enough due to too high a turnover rate.
I hope this helps ya...alittle wordy I know but I am a firm believer of this...Again, my opinion-but it makes sense to me! _________ 125gal.w/Mag9.5 return(dual megaflow)>Mag7 pump Aqua Cev180skimmer.Wave2k Hamilton Reefstar(2)250watthqi(mh)pend.a Yellow, Naso Tang Red Lip Blenny Percula Clown Demoiselles Niger Trigger F.
