No the org is scrapped LOL
The light (2x4') sits across the top of the tank, so I can move it back & forth as needed for plant care. However if you don't need that for the small tank you can just screw the light on to the back's or sides since the hood (built the way I did) slides right on/ off the tank easily.
And trust me if I(!!!) non handy man no tool experience type gal can do it for a 55g, you can sure enough do that for a 30g...only of cause if you send me pictures afterwards.
Look at your homestore of choice, ours had these pre-cut thinner wood strips (about 1/2" thick) that was real nice wood and came in strips 5.5" tall and 4ft long, perfect size for my 55g (that way your save cutting sheets of wood and they were only few bucks)
sounds good ^^ ill see what i can do!
the top for my 20gal seems to be fine
ive still be using it since i stepped on it and its ok lol depending on how the hood for my 30g turns out i might just make one for the 20 as well
