Hello.
I have been using glass tops for my 220, with no problem because they are heavy so the fish can't knock them off. Well I did some moving and now have about 3 pipes that come into the tank from the top, as apposed to coming through the back wall like it used to.
So I am going to have to put an plastic top on one of the openings. How can I keep it held down without getting strange shadows, caused by setting something down on top of it?
I thought about drilling 4 small holes one on each corner of the opening, so I could use nylon bolts to bolt the lid down. However I am scared it might mess up the integrity of the euro brace.
