what`s your favorite epoxy?

I like the plumbers epoxy because of the price, there are downfalls to using it though.  The first is you cant directly mount corals to it, although i have been able to with the aquarium grade stuff, i think the plumbers stuff might get hotter when it cures, not really sure.  The other downfall is it will make your skimmer go absolutely crazy, i learned that the hard way.  The last reason is the color, i really preffer the purple stuff but it's just soo expensive.
Just my $0.02

There is a thread like this going on RC on the CIMA board.  One of the old time reefers noted that if you use the grey stuff (sold at Home Depot and the like) be careful because it contains iron and it will feed algae.  I tried using the grey stuff once and thought it was really inferior for reef work, turns mushy easily if you have to work it much and pops off easy after weeks which has resulted in huge headaches for me.  Save yourself in the long run and buy the more expensive, reef safe green or purple type.  I myself think that the green ones work the best for the money, the purple is always more expensive and you get less although blends into the scape easier.  Just my opinion.

You can get green plumbers epoxy, it turns white when mixed and looks exactly like the stuff you can buy for reef tanks. IMO it will be fine in a small tank just don't go overboard with, maybe just mount a few frags a day it and turn off your skimmer for a bit after you use it.
