Hey Brad, I am getting a few mangrove starts from a group buy and was thinking that I could just poke holes in that blue foam construction insulation to use as floats.

Is that a safe floation system and is it ok for the mangroves as well????

Dave.: Thats the way I have mine floating in my refuge this works like a charm.

I have seen that before, but was not sure how it worked out and if the blue stirofoam had any bad suff in it.
