Now, you might be wondering, “Why in the world is there a whole post about epoxy and glue on a beginner reefing website?” Well, the answer is simple – it’s all about aquascaping and corals!
When it comes to creating those cool overhangs, caves, and stable bases for your aquascape, epoxy and cement are your best buddies. They work like a charm!
For larger aquascaping projects, cement is a cost-effective choice, especially compared to pricey tubes of epoxy. I’ve tried different cements, but I’ll share my absolute favorite below.
You’ll find epoxy for aquariums in two colors – grey, which blends well with white or grey live rock, and coralline, perfect for red-colored rocks.
Now, let’s talk about attaching those large corals to your aquascape. Super glue to the rescue! There are three types – single-use tubes (perfect for attaching a coral and tossing after use), larger tubes (better value, but be careful underwater), and gel bottles (precision gluing, but don’t get ’em wet!).
I’ve got all five options stocked up, as I find them super handy for different situations. It’s always good to have a variety on hand! 🌊🐚🔧
5. Epoxy
Ah, the infamous epoxy – it can be a bit of a challenge, but fear not! First things first, do yourself a favor and gear up with some gloves. Trust me, it’s sticky stuff!
Here’s how it works – epoxy comes in two parts that chemically react when combined. Just cut off the amount you need and knead the putty together using those trusty gloves. Once the two parts are mixed, the clock starts ticking – you’ve got about 1-2 minutes before it sets!
Now, be warned, epoxy does have a funky smell. So, brace yourself! If you’ve got a protein skimmer running, turn it off before using the epoxy. Otherwise, you might have a bubbly overflow disaster on your hands!
The cool thing about epoxy is that it can cure underwater. That makes it perfect for attaching stony corals to your aquascape!
But here’s the catch – epoxy isn’t like regular glue. It won’t just “stick” things together. Instead, it forms a cement structure around the nooks and crannies, so keep that in mind when working your aquascaping magic.
And the best part? Epoxy is reef-safe, so you can safely use it underwater in your fully established saltwater aquarium. Happy aquascaping! 🌊🧪🔧
4. Single Use Super Glue Tubes
Alright, let’s debunk the superglue myth right off the bat! You don’t need any fancy “reef-safe” or “aquarium-specific” superglue – they’re all pretty much the same. They’re just different versions of good old cyanoacrylate!
The only thing that matters when picking superglue is the consistency – go for a thick gel, not the runny liquid. That’s the real deal!
Now, I’ll admit, those “premium” labels crack me up! But hey, I do like Polyplab’s product, so maybe it’s the real deal after all!
But here’s the catch with using superglue underwater – it can be a messy challenge! Don’t expect a tiny drop to magically hold your coral in place. Oh no, that won’t work! You gotta go all in with a generous amount of glue, creating a sturdy structure around the coral and the rock’s nooks and crannies.
It’s all about building a fast-curing fortress that’ll hold tight once it sets. Now, let me tell you a secret: those super-fast 15-second claims? I’ve tried ’em all, and they’re not exactly true. You might need a minute or so for that glue to set underwater, so be patient!
To make life easier, I grab these small single-use tubes – no need to worry about wasting an entire tube! My trusty sidekick, Dana, is always ready with the next tube, and when we’re done, toss it in the trash. Easy peasy!
So, no need to splurge on fancy names – get yourself a good gel superglue, and you’ll be mastering the art of coral mounting in no time! 🌊🔧
3. Super Glue Gel Bottle
Super glue is a must-have for every household, and for us reefers, it’s essential to keep several on hand!
I prefer the one from Bob Smith, but honestly, any thick gel super glue will do the trick.
Remember, don’t dunk the bottle in your tank (that’s what the single-use tubes are for!). Saltwater will ruin the nozzle and clog it up.
Use the bottle for the first coat before placing the coral in the tank. If you need more, just ask your significant other to bring out the disposable tubes! Easy peasy! 🌊🔧
2. Large Tube Gel Super Glue
Get this glue! It’s my go-to – thick, affordable, and readily available online and at your local fish store. Done! 🐠🔧
1. Tunze Coral Gum
We highly recommend Tunze Coral Gum for frag mounting. It’s a fast-setting epoxy that allows you enough time to position the frags, but it sets much quicker than other epoxies, saving you from the hassle of holding frags in place for too long. It works exceptionally well for both larger frags and small colonies, providing a secure hold. Plus, it’s great for small aquascaping projects too. An added bonus is that it doesn’t have the strong epoxy smell that is common with other products on the market. Give it a try – you won’t be disappointed!
