Im setting up a 35 gal hexagonal tank... What do you think would be the best lighting situation, right now i have the 18 inch single strip corallife 50/50 that it came with.. the tank is about 2 feet deep.. is this enough? or what are my options.??? if i plan on usin about 40 pounds of live rock, how many inches of fish could a tank this size support?.. thinkin about ordering live rock from aquacon, has anybody ordered the ultra tonga.. is it worth it, where should i get it from??
