How do you Secure SPS Frags on Rocks?

[Spyd]

I would never bother with Ecotech glue... It costs a fortune. The Dollar store crazy glue works just the same. Get the thick gel stuff and use that. $1 / tube as oppose to $20 for a bottle... Just my 2 cents.

As for mounting SPS, I like to use a sandwich method. Crazy glue, epoxy, crazy glue on the bottom of your SPS piece then push it firmly into place. Keep the powerheads off for 5 minutes and it's set and will not move.

For epoxy, I use Aquamend because it is relatively inexpensive, safe and works very well.
