Fish Tanks for Reef Tanks

[Dorkel Marine 1]

I had a 30 gal tank with freshwater. I put live sand bed in plus about 20 lbs of rock and low and behold it started a slow leak on the bottom. Now grante this tank was about 16 years old. So I took everything out and resealed it and put some wood underneath so the bottom glass would be supported. I never realized the drop from the bottom glass to the bottom of the trim. So my question is; are there any tanks out there where the bottom glass is flush with the ground. I went to petcetera and they only had one tank with that feature. I don't want to reseal this old tank again. So where do you guys buy your tanks and are acrylic tanks any better. I'm basically looking for a tank that is flush to the ground. Thanks in advance. I'll gladly take a used one but I know this is not the forum for that. Happy Reefin George
