Ok. I had to back up and regroup. I changed stands. The shelving unit from Lowe’s is not going to work. Once I started putting weight on the unit and tank it became a little too topsy turvy for my comfort. And with nearly 800 pounds of rock, water, wood and fish I just could not risk it. Please don’t take away from that shelving unit. I will be using it elsewhere.
I went back to Bob’s Tropical Fish and got a regular stand. Little pricey but worth my peace of mind.
