Attaching Frags
 

Is there some other cheaper epoxy/glue used to attach frags to LR that is cheaper than the $20 stuff the LFS's sell?

Forgot to mention, something that works under water.

Just go and buy some quick dry superglue, works fine for frags just turn frag upside down in the tank keeping everything but base submerged then apply a small amout of glue dont cover entire base and hold rock for max 30 seconds then place back in tank. U can get ones that dry underwater but it cost too much this way is cheeper

Will any super glue work, like they stuff found at Home Depot?

Yup any kind. But gel superglue is the best

Loc-Tite supeglue gel.

You can get Aquascape milliput epoxy from JL Aquatics for $10.75 and it works great underwater and is the color of coralline algea. They offer free delivery to your door step with orders over $100

i use superglue gel from the dollar store and epoxy from home depot thats safe for drinking water (like 6 bucks)
