Hello, I am brand new to the Saltwater aquarium hobby, I have an 8 Gallon biocube with an Aquatop MaxiFlow NP302(118 GPH). My tank has very low rocks, maybe 3-4 inches from the bottom of the tank. I have pretty fine sand. I currently house 2 RBTA and one juvenile clownfish (1-1.5 inch). The flow in the tank isn't that good so I was looking to buy a new wavemaker, I've seen hygger mini wavemakers (1600GPH one) and Jebao ELW-3m, but I can't decide which is best for my tank. I need something not too strong so it won't kick up the sand and cause too much stress for my clowns. Any suggestions?
