How strong is 2 lil Fishies rock epoxy

[BioMan]

I never used this stuff before, but I'd like to bond 2 dry Marco rocks together and a shelf rock. If everything is dry and I wait the 24 hrs it says to cure, will a shelf rock, maybe 3 lbs, stay put?

Stinks. Use the water weld from HD

That bad? This is for new tank, I used half a tube trying to get these rocks together and if they separate in a few months from a snail or something I'll be pissed!

Marcorocks.com. has there putty I bought 5 tubes for our new tank. It is pretty good and ready for use after done hardening .

It works good. Just add superglue for extra strength.

I prefer Water weld, but used both for my Marco rock structure. No issues
