Are you guys absolutly sure that it is safe to put that in a reef tank? I would love to do that in my tank but it makes me nervous.

well my plans are to paint it then run it empty with plain water. Let it run then empty then add fresh water a few times. This way if there is any toxins in it then it should be washed out. On the can its none poison just flamable due to can pressure. Im sure it will be ok if not then i guess its a waste of time lol

I don't know I am going to do more reading on it and maybe a few experiments just to make sure because I think it is totally cool

This months tank of the month is all foam backing and overflow.

Also note is used GREAT STUFF and this info is from the manufacture.

Quote:

Constant exposure to water or sunlight will cause it to break down over time. If Great Stuff is going to be exposed to water or sunlight, we recommend painting or sealing it to prevent this degradation. Great Stuff is a non-toxic polyurethane foam, exposure to water will cause it to break down and crumble. The primary concern is that if animals were to eat these pieces, it may cause blockage.

The breakdown is pretty noticeable, but not major. I've seen eroded areas in between the coraline, but it's not like the whole wall is disolving on me. I suspect that coraline shoud be able to cover the entire wall before there is too much breakdown of the foam.

I know the 90 gallon in the pic above. He used the foam sealant, then about five different colors of marine enamal to creat a coraline effect. after it was cured he filled the tank and away he went. I'll vouch that it is none toxic. he even embedded pieces of live rock to use for coral shelves.

This is very similar to some of the 2-part extruded foam we use for projects at work. The sprayer has to wear supplied air when spraying it and sculptors have to wear respirators when carving. The foam will continue "off-gassing" for a period of 24 hrs after being sprayed, so don't put it in your tank or cut it before then.

I know this stuff is very dangerous before it is completely set and inert. However, I do plan on using it for my background, but I will not put in in the tank without a complete coating of sealant and only after sufficient time for it to cure.
