I have a wave2k though I haven't got around to it yet as far as setting it up on my 125 yet. One of the local pet shops is running one and it is very quiet and pushes alot of water.
The more water flow the better-though you have to be careful not to have too much flowing on coral that like reduced water flow.
Water flow is beneficial for the removal of detritus by keeping it suspended in the palegic area of your tank for the skimmer to remove it. It also helps with the transfer of carbon dioxide and oxygen by corals for photosynthesis. It carries food to sorals etc. as well! _________ 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.
