Filled up the tank today. 2028 filter output is not as much as I expected. Also, my two month old Catalina 2x24w apparently has a dead bulb. Hopefully just a bulb. I plug it into my digital timer and the timer makes a clicking noise over and over with no light on. Plug it directly into the wall and no light still. Weird. How long should I wait to trim the HC after the switch? It was already getting pretty tall.
