Hello everyone. I am looking for opinions on helping with rock shadowing and helping the backs of my across. I have a 96” tank and am debating buying 2 used 48” 2 bulb t5s to hang toward the back of the tank. I can get plenty of par just using the leds but the pucks don’t have enough spread to cover the 30” deep tank. Do we think this would help or just a waste of money?
