Hey guys, i was wondering if nitrates are skimmable. Would a skimmer, like a prism, be worth the $$? The tank that I am having problems with is a ten gallon nano. I know that it is hard to create an anearobic environment in such a small tank. I have a nice area of calurpa in the display but I just don't think that it converts NO3 to a gas quickly enough. And I am tired of doing sooo many small water changes. I've researched the refugium idea for the tank and have counted it out. So, should I break down and buy the prism or maybe a bakpak for it?? Please help :?
