So I have just recently set up a 70 gallon upgrade and had some questions. I have some old metal halide lights a growing friend of mine was gonna throw away. I took them thinking about my future reef tank. They have been in a box for years. The current orbit USA leds strip I have on my 30 gallon will not suffice for my new 70 gallon upgrade. My main question is how to properly operate these lights. I know they produce a lot of heat and are old school(still great).
what is the appropriate wattage for a 3ft 70 gallon tall?
Are there different light spectrum bulbs?
Should I buy some T5’s until I can upgrade to LEDs?
