For my newest tank addition I thought it would be fun to motorize the canopy for easy maintenance and frag placement. So here is my journey. My main concern was the brackets from the motorized legs holding the weight of the large canopy and I thought of a million ways to extend them without adding more weight. I thought aluminum but was hard to find what I needed. Then I thought steel but rust and weight played into that a lot. Then I went back to trusty old wood. I lagged the 2x6 to the steel supports of the motorized legs and it worked great.
