I had some commercial racks i used for my tanks. Here's a pic of three 6ft long tanks (110, 110, 100 gallon sizes) stacked on top of each other I had in my fishroom in the basement back in Michigan..each shelf holds 1500lbs. http://i29.photobucket.com/albums/c279/jschulst/006.jpg GoBlueCichlids www.wolverinecichlids.com ________________________________ From: Seattle_Aquarist <Seattle_Aquarist@comcast.net> To: gsas-member@thekrib.com Sent: Sun, October 18, 2009 9:52:59 AM Subject: Re: [GSAS-Member] metal tank stands Hi Ken, I have used metal tank stands for years, the welded angle iron type, without any problems. I currently have a 45 tall (about 450 pounds) above a 30 gallon (330 pounds) sitting on the basement floor. You do have to watch out for "floor loading" if putting any large aquarium or "stacked" aquariums on wooden floors. The metal stands that seem to have problems are typically the "bolt together" or "knocked down" type that comes in boxes and you put together.
