Number of shop lights over a 20g long?
I am planning on building a hood with shop lights for my first FW planted tank (I have 2 saltwater planted tanks). I wanted to know how many shop lights I should get (I did a search first, and couldn't find much on answering thsi specific question). I don't want to over do it, and have so many that my tank overheats. I also don't wanna undershoot and only have enough for algae to grow. I am plannign on leaving the back of the hood open to allow for extra ventilation since my house already stays fairly warm, and we live in a very hot part of the US. How many light strips will I need for a 20 gallon tank? Any specific brands that y'all really like, or really hate?
Your help is MUCH appreciated
