Obviously keeping up with this tank is more difficult than I originally thought. I have the 29gallon TBS package, but have only the first half of my rock. I've had it since last August. Lately though, i have been fighting a loosing battle against algea. My tank is overrun with green, red, and brown algea. The only thing i have chipping away at it is some cone shaped snails and some sea irchins. I have purchased an RO/DI unit and am going to install it soon. Other than doing that can anyone give some suggestions. Im getting irritated with it. Would the presence of the the "critter" for the package deminish the algea population?
