I want to make one. I got to thinking that theres got to be a better way than hoping and praying that the suction cups hold up on the turtle docks being sold today. So I was thinking I want to make a dock, something that will have four legs sealed to the bottom of the tank (this way the turtle can swim under the dock). The docking part would have a flat area (pretty large) along with a short ramp for it to get on/off. But what would I use to make such a thing? I want something that I can make look natural. I'd be putting it on one side of a 55gal. tank for now but I would want it to be able to be taken out and resealed into a 75+ gal. later. I guess all I would have to do is take a razor blade to the sealant.
