Hello, I’m a freshwater aquarist and I’m trying to get into saltwater without spending to much money. I was wondering if my some of my freshwater gear can be used in saltwater. First. I was wondering if my sponge filter would work. Secondly, I have two Beamswork led full spectrum lights. I was wondering if those would be able to grow corals and anemones. It is a 20 gallon long tank that I am hoping to turn into a beginner saltwater community tank. Thanks!!!
