I am about to (at last some will be saying) replace the ank I lost in the disaster last february. It was a 7 ft glass tank made by Clearseal, legal action is still pending between my insurers and the company. Anyway, after losing the bottom floor of my house for a month, I am faced with the dilemma of what to replace it with. There are the old arguments that acryllic scrathes and won't look good for long etc etc. You guys have the experience. I am going to be a little more modest this time and go for a 6ft x 18" x 18", feedback please! perhaps thicknesses would be handy!
