Not only did this product not stick, it clouded the entire tank water. Waste of time and money. The worst epoxy I have ever used, flakes everywhere and makes a mess then won’t even stick. Tried multiple ways of using and the more you handle it the more cloudy it turns your water.

Not only did this product not work, the putty is now flaking and looks like it is snowing in my tank.

Bought this assembled dry rock outside of aquarium caused protein skimmer to go crazy clouded water and led to all fish dying luckily only had a pair of clowns in tank.

Bought the other day and tried to use it. Used out of water and it wants to stick to my fingers more then the rock. As well as instead of becoming white like other epoxy. Is still tinted green. Got it to kind of work by surrounding pieces in it. But does not do well at holding on to rock

Brought this for my reef tank,gets hard so fastand it wont stick on the rock,I would like refund.

It’s hard to say since this is the first sea aquatic epoxy I have used, but when compared to our general expectation on a adhesive product, it’s actually pretty bad. I am giving it 2 because I finally got it to stick on my third try. I would best describe the adhesive quality to be that of using chewing gum as adhesive under water. does not feel sticky at all. I did mix it well and tried to not over mix it on my third and final try. it does make the water cloudy but nothin died. The gorniopora that I was trying to stick is doing well so it’s good on the toxicity. my advice is to use a good amount which is to say enough to make a level base for the attachment. Trying to keep it minimal and invisible is something I would not recommend as it probably will not stick.

Works well to connect base rock together for aquascaping.

Very happy I purchased this Product work great Will purchase this again
