hello everyone!!!
Thank you in advance to everyone for there advice.
I currently have 4 96 PC in my 55 gallon tank.
I am planning to upgrade in the future to a 120 gallon tank.
I currently have the opportunity to purchase some lights by aquamedic for a really good price.
I have been offered 250 watt HQI set up with two 96 watt PC's.
What is the difference between HQI and regular 250 Metal halides?
The HQI's look brighter and alot of people have told me they are better... WHY??????????? thank you agian
