Aquarium Advice Regular
I've been thinking of using my old 40 gallon tank and making it a clam tank. I have a 400 watt ballast that I would use to light the tank and a aquac remora skimmer for filtration. My question is though, I dont want to buy a bunch of live rock for the tank, so is there a good filter that would be a good substitute for LR for biological filtration. And if anyone has any expierience with clam-only tanks, I would be appreciative any advice.
