PC last for around 9 months. They do not heat up the water that much. PC are good because you do not need a chiller with them. However, if you are using metal halide, which do heat up the water, you would need a chiller. I currently have a coralife pro, 48 inches, 2-250 watt metal halides, and 2-96 watt actinics. The PC would be good if you are only doing
soft corals. Also, it is best to have a 75 gallon tank because the 90 is deeper and you wouldn't be able to put to many corals on the bottom of the tank. It's all relative to the coral you want. with pc you will still get good
coraline algae growth. the pc lights were not cheap new. The coralife was $200,and the Jebo was $150. If you are interested and in the area you are more than welcome to come see the lights. I have a sump for sale, too.
