I took this out of my cart at the last minute thinking I could just use gorilla green cap gel glue let me tell you without the accelerator it’s a horrible situation. Save your self the frustration and buy this with the accelerator. I was able to do a 32 gallon with one bottle of each.

I used a bottle along with the accelerator on my new reef rock and it was amazing, fast setting with real strong holding power. Also came shipped with several tops so you're not prying off the old one when the neck becomes clogged. I use it around the house for lots of repairs as well. Great Glue BRS

This product and I have created a solid bond! I guess you can say, if I didn't like this product, I would be unstuck or come unglued lol.

The glue itself is fine however my experience with it is when you let the glue sit for a while in the bottle a very thin layer of watery glue forms at the top of the bottle. When you go to apply the glue to your first frag a watery mess comes out of the bottle dripping all over your coral. (Smothering the coral and killing it) This has happened multiple times and killed multiple corals. After you get through the top watery glue mess that first comes out of the bottle the rest is fine until you leave it sit again for next use. From Product Page- Special Note: During storage, it is common for the glue components to separate, and you may encounter the glue dispensing in a very runny form. This is easily remedied by shaking the bottle or kneeding the tube several times to mix the glue components back together.

Used this for gluing several frag types to different coral pucks and all snapped off with very little pressure. Glue did a horrible job sticking to coral and pucks.

I picked this up to build my aquascape and glue corals to my rocks—and guess what? It’s glue, and it does exactly what glue is supposed to do. It holds strong, works underwater, and most importantly, doesn’t harm your fish. Performance-wise, no surprises here—it sticks, it stays put. I’ve even started using it for random fixes around the house. It’s basically become my unofficial handyman in a bottle. The only real downside? The cap. If you don’t tighten it properly (or if your wife “borrows” it and forgets), it can dry out. A cap design with a built-in needle, like some other brands, would make a big difference. Overall, I’d recommend this to anyone—reefers, DIYers, or just anyone who occasionally breaks stuff. It’s simple, it works, and sometimes that’s all you really need out of life… and glue.

I used this for aquascaping and it worked fantastic. I also used the accelerator spray and it was cured and hard in less than a minute. Yes I got a ton of it on my fingers, which lasted for more than a week.

It does everything you think it will. Nothing more, nothing less.

This glue is an absolute must for aquascaping. It's super thick and holds rock together almost instantly, especially when used with epoxy. I added onto my aquascape after the tank was already cycled and the glue held perfectly underwater. Just don't squirt this glue bottle under the water or water will suck back up into it.

I love absolutely love this glue. It holds very well. Mixed with some epoxy the rockwork is now a brick wall!

After trying what feels like a dozen glues I ordered this. I have always struggled with and hated gluing on frags or fixing aquascapes. This stuff is super thick, like toothpaste, so it stays in place. Coupled with a bit of accelerator it holds almost immedately and gives the best bond I've seen yet. Will never use a different glue!

Don’t forget safety and don’t leave out where kids can get to it . Mine glued the fridge shut and glass cups to the table

This bottle lasted me a very very long time and it came with a replacement nozzle in case the first one ends up getting clogged up over time. Will only use this for now on.

Still decent but not as thick and last few bottles very strong chemical smell.

Great glue and good value. Have had no issues being able to use the same bottle for over a couple of months now.

This product is fantastic when paired with the instaset!! Building a negative aquascape couldn't have been easy and quite frankly I don't know how you would do it without the BRS Glue/ Instaset combo. Thanks BRS!!

This was such a needed size to be able to complete my aquascape! Very easy to use and the thick squeeze bottle makes its so simple to apply to rocks!

Believe it or not it's actually very hard to find CA gel In large quantities and when you do they can be super expensive. BRS nailed it down with a performance product at a great price. try it out.

Strong bond. Thick and can even fill spaces with great strength. I have been using for a week for hours at a time in my garage with no issues, except accidentally getting a little in my hair (oops!). Make sure to use with the Insta-set Accelerator - this is a must. I reviewed that as well. Reading a few reviews below, I would like to make a few follow-up statements. First, glues and the accelerant contain hydrocarbons which are volatile. That is why they evaporate so quickly, turning to gas form which can be breathed in. Take caution to use where there is good ventilation. Always common sense with these types of products. A reviewer above states this is a different formulation that is dangerous. I am not aware of any previous formulation. Would be nice to have BRS weigh in to that comment. Second, for the gentleman who had poor bonding, if you bond a shaky surface to another, it won't hold. Case in point, I am using with Marco rock and there can be sandy, powdery pockets, especially when broken by chisel. These have to be carved away to expose the hard surface underneath. Once a solid surface is glued to another hard surface, there is just NO way this stuff failed. I have spent hours for over a week every night making multiple bonds on my aquascape. This stuff is amazingly strong.

Very happy with this glue. Works very well and holds my corals in place right where I want them. Will keep buying this glue.

I read the negative reviews and was concerned but ordered anyways. I'm glad I did because the product worked very well and I used it alone to secure my aquascape together. It did seem to cure a bit more slowly than other brands of super glue gel I've used in the past, but it wasn't anything extreme. I like the bottle and the nozzle makes it easy to use and get into harder to reach places in the rock. Highly recommended.

I am very happy with the glue. The 10oz bottle was the perfect size and it comes with 2 additional applicator nozzles. Definitely purchase the recommended quick set spray. This allows the glues outer shell to harden quickly and then wait tell the glue sets completely before trying anything to crazy.

This glue use to be amazing, my company rock scaped many tanks and used it for all our frag gluing. Since a lot of products on BRS started changing in quality this one has taken a major hit. I recommended this product to many of our customers and now because of 2 reasons I can no longer support it. #1 Safety Months ago I noticed a change in how the glue worked under water and above water. The largest concern with the glue is how it can sneak up on you even when wearing a mask and proper ventilation. We have had 2 recent issues where 30 minutes after gluing my employees have to use inhalers for 3 days because it hurt their lungs. #2 Consistency BRS glue had been known for “Extra thick” and the glue was amazing for being thick sticking rocks and plugs in hard to achieve angles. Unfortunately now the glue is more of a mid range glue. The new formula that’s being produced has created the glue to not be as thick and dangerous with its toxic scent. If you are looking for a super glue in bulk this product works great. However keep in mind it’s very toxic. I give the product one star because it does not compare to the original product BRS sold and it’s very dangerous.

Yep it’s thick glue! Worked well for my aquascape and I have had zero issues with it. HOWEVER I managed to get glue on EVERYTHING I got close to and at one point I even had it on my lips!! It’s a great price for the amount.

Worked great for aquascape...

I purchased two bottles of this bulk reef supply glue, it was anything but thick… I went to do my aquascaping, the glue came out like water, so thin I couldn’t use it for the purpose intended. I guess I’ll use it around the house, hate to toss it. If buying this for aquascaping, go with epoxy ATM…

I purchased this glue to put my aquascape together, wow whe combined with insta-set its some amazing stuff, I absolutely love how thick it is. My only complaint is the smell but I have never used a super glue that didn't stink.

Honestly, this is the first BRS branded item that I've been disappointed in. Adheres well to dry surfaces but the rock surface in the tank gets poor adhesion. Many if not most of the frags I attached with this glue shortly fell off the rocks. I went back and reattached with standard superglue Gel from the big name cyanoacrylate glue company that you can get anywhere and they have held ever since. Based on the reviews, maybe I got a bad batch, but based on my experience, I was disappointed.

This is the best glue I have used. Ok to be fair I have not used every glue on the market but I have used a lot of them. I have come to make this my “go to” glue. I love that it’s a large bottle and it flows easily out the nozzle without getting clogged. Plus it snows with a couple extra nozzles just in case. So, yeah, my favorite glue as of right now.

Works as intended, again, shipping was terrible, crushed box, caps off everything, re taped box and not very well

Glue is great, it’s what I expected, the shipping process not so good, box arrived crushed, it had been open and taped up again and not taped very well, caps were all off the products like it had been tossed around pretty good

I used this for aquascape, work great with INSTA-SET SUPER GLUE ACCELERATOR

After dispensing a tiny part of the first section of the bottle initially, the glue start to get extremely thick, i use this to propagate all my eBay sold corals, its like a viscous version of putty

Consistency is thick and works great for frags. Comes with extra caps which is a must for a bigger bottle. Can’t really beat the value and quality. 2 recommendations I had were -Liquid seems to settle on top so if I don’t shake it each time then I get watery glue, so could be more homogeneous. -Could use a needle cap so it keeps the tip clear between uses. I Still give this 5 stars. Glue gets expensive when doing a bunch of frags and this is exactly what I need!

This is the best glue ever, I tried all other possibilities, but no one was better than this. Too bad someone here did put 1 start without even using the product. But here it's mine. I higly recommend this product

This glue is awesome! I have yet to find glue this cheap, and effective for gluing frags to plugs, or to my rock work. I love having the large bottle, I never have any issues with it drying closed, except occasionally having to peel some dried glue from the tip. I’m about to order my 2nd bottle!

Previously I had no problems with BRS glue but these last 2 bottles bought have been disappointing.

big fan of this glue, super thick, cures fast easy to make frags
