Tony, Sooooo green to look like algae? Brown to match the diatoms? Maybe dark red to match future cyano outbreaks? Are you saying my tank is doomed to fail? I'm keeping your chalices now.......
Just go to petsmart and get a coral reef background and stick it on there.
Petsmart background will not stick properly.
How about spraying back with whatever coloer using can spray from HD ? I used blue-metallic - it reflects light better.
After a while, your background will be covered in coraline and color of the backwall will not matter.
Pump is here!!! Now to wake Olivier up! Going to try and get the stand done this weekend and get the tank cleaned up too. Then it's off to HD to get flexi pvc and a few fittings!!
