I had a leaking 350 gallon tank that has 26 seams. You can just imagine the nightmare! No one would touch it, unless I brought it to them. It takes 5/6 men just to pick it up, so that's not something I really wanted to do. I just wanted to say Daniel, of Precisionaquatech.com, did a fantastic job. We started filling it on 06/05 and everything looks fine! Knock on wood His main job is making and selling plankton, but if you ever have a leaking tank..... he did a wonderful job for me and I am grateful. Johne
