Is my epoxy defective, or is it just me?

[christyf5]

Which brand of epoxy was it?

[michika]

It was Holdfast, by Marineland.

On a curious note, this brand isn't as stinky as the other's I've used before. Does the smell correlate with effectiveness?

In my experience, the epoxy never bonds to the rocks. It's by making the epoxy fill into nooks and crannys so that it bonds to itself with anchors in the holes of the rocks that makes it stick. Hope my 2 cents made sense.

I am using Tunze epoxy from J&L bonds, holds and easy to remove.
One pack i bought over two years ago still ok.

Is anyone else's epoxy boyant?

I crammed my stuff into the rock as much as I could, and later it kind of just floated off. Very odd....

The stuff never works for me. I've had entire colonys held in place for 6-8 months they the epoxy fails with no outside influence and crash.

I now use epoxy to hold the frag then I use some of OA's super glue to glue the epoxy to the rock. Works very well

Jason,

So your saying you superglue the frag to the rock, then pack or epoxy around it? Or are you saying that you epoxy the frag, then superglue the epoxy to the rock with superglue?

Can cyanoacrylate (sp?) be used underwater? I feel funny admitting that I've never epoxied, or glued frags to actual rock, other then rubble...
