I'm starting a new 55 gallon SPS tank with 30 gallon refugium.
I'm going to install two VHO URI actinic bulbs in the canopy and get 48" maristar two 150 watt HQI with T5HOs. I can't decide either to go with 150 watt or 250 watt HQI. Could two 10000K 250 watt be too bright for 55 gallon tank? I have geisemann 230 with 150 watt 20000K on my 29 gallon mini reef but the brightness has gone down quite a bit.
Thanks for any help,
Hanseung
