I'm wondering how much cheato I would have to harvest to account for a cube of food input, and how much space I would need to grow and harvest that much.
The reason is that I'm thinking of setting up another tank, a 25 gallon cube, but I'll have the space in the cabinet for a 20 long sump, or maybe even a 30 breeder. Given that much space for a "fuge", I'm wondering if I could grow enough cheato to "scrub" the system clean of N and P. I've got plenty of LEDs and heatsinks for 100+ watts of grow light I could put on it. Any thoughts? One cube a day of scrubbing power should be plenty for what I plan to have in the display tank.
