It sucks that I dont have a camera, cause my foam project is complete.
I constructed 2 islands, to totally encase my plumbing, in each back corner of the tank and then I built a "rock bridge" between the 2 islands.
I used a file and a scalpel to shape the foam after it dried and it actually looks like rock. I finally found some marine paint, yesterday, and paited it yesterday.
The tank is getting filled today, to check for leaks (this is the first time it's to be filled after I drilled it for internal plumbing...lol).
