Beautiful tank indeed! That's how I want my tank to look. So pretty. Hmm. Don't the biggies go after the little fishes, as snacks?
How would you gauge your light quantity, for 4 T5HO bulbs? Too much, too little, or just about right?
I'm trying to decide how many 4' T5HO bulbs to install on my own tank (60"Lx18"Dx26"H) which is rather similar to yours. My canopy holds three 4' T12 old fluorescent bulbs that don't seem to provide enough light to grow my plants. But other (sticky) MFK forums say that using 2 T5HO bulbs would be almost too bright, and would just lead to algae problems. Do you agree? Or not? How many would you recommend I use? I don't really want to add CO2. Do you add CO2?
