Gap Between Background and Glass

Sondre95 · Thursday at 3:56 AM

Hi,
I have a 190-gallon tank with a 3D background that isn’t as long as the aquarium itself. This creates a gap between the background and the side glass, and some of the fish swim behind the background. Does anyone have any ideas on how to seal the gap in the cleanest or most visually appealing way?

Thanks!

The best way would be to drain the tank and attach the background with silicone. However that may not be practical so stacking rocks against it until it is snug against the glass would be another option.

Maybe patch it up with some egg crate and then try to paint it a matching color or place some plants or wood along side of it

I had the same problem. I used a leftover piece of another slim 3d background. It looked OKish and did the job.

Milingu 's solution above is probably the most natural looking. I have a background with the same issue and used strips of Poret ® foam to fill the gap. I used black and it doesn't look too bad. Too much Java moss in the way to get a photo.
