I have two ballasts and end caps for PC
lights that I was going to use on a FW
planted tank a few years ago but never followed through with the plan. So they have been sitting around collecting dust. Well, I have decided I want to do another SW
tank and I am debating on a 20L and a 29. With the 20L I am not too concerned about using PC
lights. But the depth of the 29 is 6 inches deeper so I want to check to make sure that these lights will still work. The ballasts I have will allow me to run as many as four 65 watt bulbs. Also, if I go with the 29 gallon I will run it with a DSB
so that will take about 5" away from the depth of the water. I am not looking to keep any high light corals, just low and medium light stuff for now and while the PC
's are running I can save up for a T5 setup.
