I want to set my refugium up with algae for lowering nitates and also put some copepods (or something) in there for added foodsource for my green mandarin. I'm just not sure what species would be best for a smaller refugium, it's a hang-on in-tank. Any on-line distributers anyone knows of? I'm thinking indo-pacific.....just not really sure what to order. I know I should just ask Gerald.....
