So I started to titebond the background today. First I tried a mix of titebond and coco-fiber... it was thick and pastey and a little hard to work with. So then I decided to just paint the titebond onto the foam and then pack on the coco-fiber. That was so much easier! I took a couple of pictures but they are hard to make out because the tank is not standing up right now and there is coco-fiber dust all over the glass. I'm not going to clean it until I'm completely done making a mess LOL
I can already see some bare spots I'm going to have to touch up in a couple of days. I'm pretty happy with it so far
I'll post pictures of this step after I have done the touch ups and have cleaned the glass
