Do the backgrounds discolour your water?
I purchased the flat sheet Universal Rocks background from a bulk roll at my LFS.
The background is very dirty left my hands black while handling it. I wiped the back of it clean with several wet paper towels to remove the film so the silicone would stick. I rinsed the front with warm water before filling the tank to clean off any residue. I filled the tank last night and this morning the water was brown, and a brown film on the glass after I drained the water that I had to use a razor to remove.
I have well water and used Seachem Cichlid buffer to bring up my PH. I had no substrate in the tank. I never had this problem with other tanks. The only thing I did different was use the background.
