The center Brace on my 200 broke I purchased a 1/2 thick piece of acrylic to replace it the salesman at the plastic shop said silicone will bond to the plastic. It did for 1 week the new brace was on the bottom of the tank this Morning with no silicon sticking to it. I had left the clamps in place for 4 days after putting it in place. Do I have to do any thing to the plastic to prepare it? Or do I need to spend the big bucks on a piece of glass? yes there in water and fish in the tank
