I am planning my upgrade and I am looking to get a MH
fixture from Current. Its 2x150@10K + 2x130PC Actinic with electronic ballasts'
The problem is, I can not hang it over my tank, so I will be using the "legs". That will place it appox 2-3" above my tank. The tank dims are 48x18x20
Should I be concerned about heat? The tank will have at least a 20g sump and a separate 10g fuge. I will have a heater in each of the sumps/fuges and there will be no powerheads in the main. Flow will come form the returns and a closed loop system. I will probably have a small fan in the cabinet to keep that area cool as well.
My current set up only has PC
lighting, so I do not know what to expect as far as heat exchange. I can not afford a chiller at the moment, although I will have one before next summer. The tank should be up and running in Sept, so hopefully the weather in so cali will cool down a bit.
Sorry for the long post.
