Foam Rock Walls Builds

The epoxy is used for attaching sand to the foam after it dries. I've also seen people throw the big grain salt(epsom?) on top of the foam when it's expanding to create texture, then filling the tank dissolves that salt. There was actually a Reef Central tank of the month who used pond foam a long time ago, so the stuff works pretty good. I built a 29 gallon tank for my brother using the stuff and I think it turned out pretty good. I'll see if I can find you some links for what I read when researching it.

 

I thought this guy did a pretty good job: http://reefcentral.com/forums/showthread.php?t=1917733

Here's a quick search for "foam wall" title search on RC, I'll try to find more links when I have more time: http://reefcentral.com/forums/search.php?searchid=5134801

I don't know about the UV part, but if I could do it again, I would use the black pond foam. I used Great Stuff (red can) and have ammonia and nitrates issues for the longest time. The epoxy is to hold the sand on the foam, but it also helps protect the foam too.

 

This is what I had to do with mine, and still if I don't keep up with regular water changed my ammonia and nitrates will still start to spike.

 

Seascapes used a lot of foam on their 1500 gallon tank. It looks really good.

 

I used Portland cement, oyster shells, and crushed coral on my wall. no foam

 

we just got some of the black pond foam at menards we are putting one on a 220

 

There was a guy in the QC area that did one of these, Nuccatree I think his name was. One thing i remembered him having issues with was the buoyancy. He had to add much more rock and stuff to weigh it down enough because of the foam.
