I think a Catalina 3 bulb T5HO on it's legs is considered High light. I feel the tank is low tech, no co2 only root tabs. Very low maintenance, just feed and top-off. No algae problems.
Wow that is an amazing tank. I always thought high light meant Co2 needed to be injected.
To me low tech meanslow to medium light which = low maintenance.
