6 bulb t5
im very new to planted tanks so i need some advice for my build. I came over from the reef side and have a 66"x22"x18" tank with a 48" 6 bulb T5 pendant (ATI Powermodule). i was wondering if that would be too much light for an Iwagumi setup?
would i better off swapping it for a 60" 4 bulb sunpower?
