For rimless I wouldn't go more than 24" high.
I wouldn't take issue with what was said about the height, but I'd add that there's a limit to the breadth of a metal halide bulb. Even if you opt for the 250-watt bulb, you shouldn't expect it to have the capacity to provide sufficient lighting for plants in an area of more than a 2-square feet below it. So , if your plan is to have your tank be 43-inches long, then you'd need two MH bulbs to cover that length if your design plan includes having plants throughout the tank as opposed to concentrating them in one area.I am planning on having a large rimless tank made. Dimensions being 43L18D
I would like to have it lit by a metal halide pendant. Someplace between 2-3wpg. The two common sizes I have seen are 150 and 250 watt
My question is, how tall should this tank be? whats a good height for planted tanks?
That is correct.Here's the math, I think :icon_ques
43" ÷ 1.618 = 27"
18" * 1.618 = 29"
CoolI have an extremely overbuilt buffet that I am using for a stand. Its length allows for a footprint of 18x43, which visualizing, looks quite nice.
