looks nice,how do you keep your nitrates and phosphates at 0? I run a GFO and a plenum with live plants to take care of nitrates,having a difficult time with po4 for some reason at .1,thinking of running a geo reactor with zeovit which will be my next project for my reef tank. Nice looking tank,good growth,is that the fad of reef keeping in europe,the zeovite,for some reason everyone from the nethrlands to finland uses the zeovite and swear by it. I know I saw an awesome dutch tank which had a geo reactor,GFO and zeovite in one set up and looks beautiful.
