Sponges are filter feeders so the placement in a location where they receive a moderate flow of water is essential to carry food and nutrients to them and rid waste at the same time keeping detritus and algae from accumulating on them reducing water flow into their spongocoel, possibly leading to death.
Lighting isn't very crucial for sponges, but water flow and reduction of air bubbles and contact with ambient environment is crucial to their success! _________ 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.
