I have a 35 gal hexagon all-glass saltwater tank set up. Reefscaping has been tough. I need more live rock. I would like to add mushrooms and annenomies but am concerned with the lighting. The tank is quite deep. It is 24" from the top. what lighting is best- have a 18" t-8 coral reef 10,000 but switch off with 50/50. i would not like to add any inverts without proper lighting. is what i have ok?
