I have got a 300L tank full of water atm, there aren't many fish in there, only 4 clown loaches. I got 3 Juwel str 600 backgrounds for my birthday yesterday to fit into my tank, but it allready has water in it. Can I put the glue on the boards and stick it to the tank with water in it? or do I have to drain all the water?
thanks for any help
