 best t5 bulbs money can buy?
just want to keep this simple. what are the best bulbs i can get for my nova extreme t5 ho 4x54 watt? i have about 10 corals mostly lps and a few leathers. some zoa, and stars. what would be the best color combination for my corals? i prefer the look of 460nm over 420nm if that helps, and my nova extreme lights say slim paq is that any thing different than regular t5 ho? and possibly a reliable site that i can purchase such bulbs? |
