My local shop has been running a reef tank on an Caulerpa scrubber called an "ecosystem". Apparently that's the only filtration they use and the tank is beautiful and nitrate free after six months, I haven't bought any equipment yet but this method seems far more attractive than the skim & trickle setups. Also, they're charging $500 (canadian) for the unit. My question is, does anyone know whether this is a good option and is it tried and tested?
