Salt (thought I am biased). I honestly don't think it is that hard. My first reef tank under PC
bulbs (24g jbj nano) is going great 4 months in and corals and coralline are spreading rapidly. If you're willing to dish out several hundred dollars I'd go with salt...It's just so much more fascinating than fresh.
Then again I live next to a ground spring fed creek that is more interesting than any fw
tank I've ever seen.
So long as you dilligently change the water with high quality salt, top off evaporation with reverse osmosis water, start off with high quality rock and sand, and have optimal flow and filtration (skimmer unnecessary in smaller tanks) SW
is the way to go.
Scottay, I have a maxijet and have no problems with the sound. They are bulky which is my only complaint, but as far as circulation goes they are 3 times stronger than koralia for the price.
