| when should I replace lights?
Hello people,
I haven't post in a while b/c my tank has been up and running pretty good.
Currently I am using 4 VHO's ( 2 super white & 2 actinics){ 440 watts}
How can you tell the lights need to be replaced? I've had them for about 2 plus years and they're still going.
One more thing, do I need to replace the ballasts too???
Thx
