You may already know this but I'm compelled to share this tidbit. Underwater epoxy is a putty and not an adhesive. Ie., if you use it to "stick" one thing to another, you're going to be frustrated because it will fail 19 times out of 20.

Instead you have to use it as a filler and fill in gaps and then let it harden. So to make two rocks stick together, you have to set them in such a way that they sit together naturally, and use the epoxy simply for stability support.

If the rocks don't fit together naturally then the epoxy will fail since it has no rigidity during the cure process. Instead, you'll have to shunt and shim with rubble, or take the rocks out, drill them and insert rods (acrylic, fibreglass, pvc, whatever) to form the structural base.

Hope this info helps!

Thanks Tony! I did know that actually but this particular brand just SUCKS! I have used the two part putty with pretty good success but this stuff I used is a single one part something or other kind and I hate it! It either sets too quickly or it just doesn't "adhere" to anything...even after jamming it in the cracks!
My rocks are actually fairly stable with out anything at all...sorta like a puzzle. I have a few ontop that could use some stabilizing but the base structure is pretty stable...I am comfortable with it anyway. I was using the epoxy last night to place some corals that keep getting knocked down...rock on rock and a couple frags needing positioning...have to run to RC to pick up the good epoxy!

New Bulb...Any color difference?

Wowzers! I definitely see a difference! Fluorescence in the tank has much more punch now for sure!

I agree, nice re work on the aquascaping as well.

The greens, oranges and yellows are definitely brighter now. Nice!

Looks great Carmen! What a gorgeous tank!


:biggrin:

Thanks for looking guys! I think the colors are more their "true" colors. Not as "blue" but still makes the colors brighter.:mrgreen:

now if only I could figure out those microbubbles....:neutral:

My new SPS "frags"....well colonies really (the Milli is bigger than my hand)...from a very generous friend!:wink:
Can't get any pics better than that til I invest in an underwater camera! Camera just won't focus through the curve and then there's the microbubbles...
