Didn't do the job, sets too fast, doesn't work unless rock is totally dry

There was really nothing i liked about this product. Kinda pricey, does not work under water, dries super fast, as in doesn't give enough time to work with it. You also need a lot of it, the one container didn't even last through putting 4 rocks together. You also need to be quite exacting in your measurements or you will not get a workable mix. In short, for me it was a waste of time, i went through the entire jar without getting the job done, and moved to another product which did work on the first try.Hide
CONS
Have to use a lot of the product for it to work

I attempted to use this on my DRY rock aquascape. I already had the drilled & plugged. I was attempting to use the cement as a reinforcement around the plugs/stakes to make the structure even more solid. I had areas where the rocks wanted to turn a different way than I wanted them to be so I was using this to avoid that. It was mixed the correct consistency & dried quickly. It actually seemed like it was going to work perfectly.... but after a few hours would crack & break up. I tried to use this multiple times yet always ended up with the same result!! Ended up using epoxy instead & for now that has worked (I find the epoxy usually eventually lets go too tho).Hide
So I used this on dry rock for my new set up. Worked great. However in the nyos video it showed it holding a rock that overhangs in place. Couldn’t get it to do that.

So I used this on dry rock for my new set up. Worked great. However in the nyos video it showed it holding a rock that overhangs in place. Couldn’t get it to do that. But as long as everything is stable this stuff works great once it hardens. I can pick up my entire rock structure and there is no give. I don’t know how it works under water but outside, I’d highly recommend this. Work in small batches though because it hardens pretty quickly. Probably 2 minutes. Then about 15 until you can start moving stuff around.Hide
I gave it a try and measured out exact proportions; round one, I found that the working time was just way too short and was setting up before I could form four blobs.
If you are going to try it, my recommendation is to use citric acid which will extend setting time.

Requires users to be EXACT with their measurements and do not mix under water.

I've used this product multiple times and have went through 3 containers. The bad reviews on this site are from USER error. If the measurements are slightly off it will not work right. However if you are actually sticking to the directions on measurement than it will work extremely good and form a very strong bond. On my first build I had to redo it since I measured my tank space wrong (those darn overflow boxes) and in order to get my rock broken back into smaller pieces I had to use a hammer to break this cements bond. Do not try to use it under water. Remove rock, then dry it off and use it. You have only about 3-5 minutes at most from when you stop mixing to when you apply the mixture before it hardens.
DO NOT MIX ALL AT ONCE. Take small amounts and mix them up and keep making more small portions until the job is complete.Hide

Trying to apply in the water: impossible. It just dissolves and makes a huge mess of cloudy water. Whatever remains just falls apart shortly after.
Applying outside of water water: fine, except it doesn't hold well on wet rock and I'm too concerned about keeping anything out of the water the amount of time needed to let it dry enough for this product to hold.
I gave up on using this to attach coral to rock. I also gave up on using this to hold pieces of live rock together. I don't have any dry base rock to try this on so I can't speak to that but I imagine it would work well in that application. Even though it claims to harden in 2 minutes, I have never found that to be the case. It has always taken at least 10-15 minutes.
This product also caused a major cyano outbreak in my tank, which is why I suggest staying away from it.Hide
