3 Foot High Tank

[scubadawg]

I have a 29.5" high tank, don't do it, go 26" max high, too hard to aquascape

Unless you have really long arms

I do believe leds will penetrate deeper ad they are a more concentrated light source vs. T5. Also different optics will give you more spread or more depth. As for the depth of the tank, a tall tank looks stunning but make sure you are able to get it in it for aquascaping.

My 300 is 30" deep and it is a bit of a pain to work in, I would not recommend going 36". My LEDs are doing great to this depth.

My tank is 30" deep, and I wouldn't do that again. It does give me added volume for the area of the tank, but it really is a nuisance to work in. I have a Vertex LED fixture which lights very well at the depth, I don't even have it set to maximum out put. I originally had 250W MHs on it.
