Help with fixing the background of my tank

[BaileysTank]

My tank is filled with water and is on a stand and has been that way for over a year, unfortunately I didn’t put a background on when it was empty and due to all the corals in there I really wouldn’t want to drain it so what are your guys ideas for putting a background on my tank?

Hi, how much space behind?

Here’s a picture but it’s pretty much a 5 inch gap

Try this out it can easily be replaced too if needed and comes in different sizes i have it on mine right now and it looks great its just static cling


Coavas Blackout Window Film: 100% UV Light Blocking Static Cling, Two-Way Privacy Black Opaque Glass Film, Room Darkening Frosted Non-Adhesive Removable Window Tint 17.7"x 78.7"

Since we have overflows, pvc, and some things we can't move I'd think a normal black background with a spot of spray adhesive here and there(do it outside) and slide it behind. Use something to flatten it to the tank.
Otherwise I'd say rustoleum 2x Ultra Cover and a 6" foam roller with a foam brush taped to a stick to get between pvc/ overflow and glass.

The stuff i sent is non adhesive and sticks fantastic its not all that expensive either. That way you dont have to glue or anything take measurements cut peel and install.

Either of @Billabong s methods would work as well. Good looking out @Billabong

Like color forms, that's pretty nice!
