    Great tip. My problem with epoxy is that it drives my skimmer crazy and I usually have to turn it off for about 12 hours or so. Super glue doesn’t have this problem so I like to use the super glue gel if at all possible with a added agent that allows it to set up faster. Super glue also drives me nuts because after I use it, invariably by the next time I need it, the nozzle is usually clogged. It also doesn’t seem to be as strong as epoxy for larger rocks. I wish there was a “one stop shop” compound that worked well for what I need and did not have all these annoying problems.

    Nice trick 😀 I’ll try that … I’m due some repair work and a move around soon…

    I’d love to hear from the people who didn’t like the tip … if you’ve got the bottle to say what you don’t like about it then maybe you might help Mark out and your fellow reefers if you give your reasons rather than anonymously drop the thumbs down … 🙂

    Hi Mark, good tip just want to know do you use ordinary super glue or a special aquarium safe product, I’ve bought this gel by two little fishes which works well if you hold the piece still for 20 seconds, but this isn’t always easy, so if possible I remove the rock & do it over a small tub then stick it underwater right after mating the two pieces. Love the Monday noon Question session keep up the great stuff.

    RE: Leonard, I found an easy way to keep your super glue bottle from clogging at the end. Just take a small nail or large pin & insert it in the end! Next time you go to use it pull nail or pin out & your ready to go! FYI this also works with any adhesive bottle, it seals air from getting in thus drying & clogging the end. Hope this helps!
    Great tip Mark, really will save my nerves!!!

    Leonard and Pierre, what Mark had in his video was the Coral Glue made by EcoTech Marine. I have a bottle and this stuff works great. Granted I have not had it for a super long time, but so far when I have gone back, the top is not glued shut like other products. It says on the package that you can extend it’s life by putting it in the fridge which I have done, so not sure if that helped on it not glueing shut or not. EcoTech does sell replacement caps, so even if it does close up, you don’t have to waste the rest of the bottle. As I said, my experience so far is brief, but I have seen a lot of high recommendations, Mark has recommended it, and so far I love it. Here’s a link to Mark’s video when he first reviewed it. He did this in May of 2011 and he is obviously still using it since it’s in today’s video, so it must be good.

  • Pierre – Yves Bouic & Leonard…Brian answered the question for me in that I use the EcoTech glue. The cap comes with a needle installed so that prevents clogging. You can also buy replacement caps and tips just in case. I use the EcoTech glue on all my builds and corals and I’ve been very happy with it.

    Just put your super glue in the fridge it lasts WAY longer that way.

  • Cristian Albu says:

    I would also have to suggest putting the gel superglue in the fridge. I use the ecotech glue and always cap it back up, shake it so all the gel is towards the nozzle and put in the fridge with the nozzle facing down… so far its never ever clogged for me/.

    I could be wrong but I don’t watch many fish guys but I thought it was you Mark that had a u-tube vid out on this glue that can even be used under water can’t remember who its made by but its on salty

  • Stu says:

    Hi guys,

    Could someone recommend a brand of super glue that’s ideal for Reef work?



  • Greg says:

    I am a newbie to coral…my questions is, once the coral is glued to a frag, can it be placed in the tank immediately or do you put it in a holding tank for a certain amount of time (I’m assuming that this superglue is an aquatic-type of superglue?
