You can run a wet/dry with really good results. Everytime you do a water change, make sure you ONLY vacuum the sand, and you'll have a great tank. When I had my tank, every water change had tons of fish poop, so it kept the water crystal clear. Also had a synodontis catfish which went well with the alkaline tank.
I had a 55g with AC's, all different types, electric blues, bumblebees, yellow labs, and a bunch of others. I buffed with AC buffer, and did weekly water changes... the tank was awesome...had tons of babies.
I always kept the lights out unless I wanted to view it. I had absolutely no algae too. Worked great.
There you have it.
...I then got bored, wanted to do salt, and the rest is history.
