My DIY LED
stand is cheap made of 1/2" EMT conduit. Costs me less than $20. It sits on an inverted T shaped wood with a stopper at the bottom against the wall. I plan to do the same on my 150 gal
with 3 of this. It's pretty neat cause it hides the electrical cord with tie wraps to the conduit. I have to paint them with black to protect from corrosion though. No pipe bender necessary. Just use bent L-bows and compression couplings.
