Two Little Fishies AquaStik Red Live Rock Epoxy Putty for Aquariums, 4 oz

As usual another two little fishes products work great. If your new to using this stuff I suggest you check out some YouTube videos on gluing corals to rock work. First of all don't expect this stuff to stick to the rocks or corals. It will stick a bit but will not really hold on for very long. You kind of mix it into the shape you need then put a generous layer of Cyno based glue like Gorilla Glue or anyone of the dozens out there. Mold the part with the glue onto the corals base and try not to get any on the living part of the coral. Then quickly flip it around and apply Cyno glue to the other side that will be going on the rock and as soon as that is on quickly submerge it and mold the other side onto the rock and hold in place for a minut or two. The cyno glue creates the great bond and the putty creates the moldable foundation. Also it's a good idea to clean the area on the rock with a toothbrush to remove any grit or ditritous. Also watch your Protein skimmer very carefully. The Putty will send it mad and it will overflow within minutes. I typically clean my skimmer out before starting and then lower the bubble level until the skimmer stops reacting to the glue and putty. Also wear surgical gloves or your going to have cyno glue sticking your fingers together. The glue dries very fast when in contact with the water and if the tip of the cyno glue bottle gets wet the glue inside will harden very quickly.

Blends in nice with coralline colored rocks. Perfect for reinforcing glued rocks on your aquascape! Use it in tiny pieces at a time as it starts to cure relatively quick.

Works very well especially if you use a bit of aquarium safe super glue first before using the epoxy. Only downfall to this product is that it has a horrendous oder. Overall I give it 5 stars due to it's ability to hold big pieces of live rock together quite nicely.

The Two Little Fishies Aquastik Coraline Red Jumbo has been a significant addition to my marine aquarium maintenance toolkit. The color matches perfectly with coralline algae and live rock, which provides a natural aesthetic to my tank that I highly appreciate. This putty has proven to be quite useful for minor adjustments and fastening small elements within my aquarium. It adheres reasonably well to both corals and rocks, and after some time, it becomes virtually indistinguishable from the natural surroundings. I admire the fast drying nature of this product. This feature is a double-edged sword, though; on the one hand, it allows me to quickly set my underwater landscapes, but on the other, it can sometimes be challenging to use because of its rapid setting time. One key point to consider is that it does have a tendency to make the water a bit cloudy initially. However, in my experience, this issue resolves itself with time and some filtration. Regarding the consistency of the putty, it can become quite soft underwater, which might be different from what some users might expect. However, once you get the hang of it, this feature can actually be quite beneficial for molding and positioning. In summary, the Two Little Fishies Aquastik serves its purpose well for small to medium tasks and brings a seamless look to the aquascape. It could be improved in terms of its usability and initial water cloudiness, but overall, I believe it to be a useful tool for any marine or reef aquarium hobbyist.

Never does harden underwater, yes I followed the directions. I used it to stick two rock structures together. It's like filling in a crack with grey putty. I have to be careful when vacuuming or any thing not to touch or it will move , and I then have to remold it and stick it back in the crack. That's right after a couple months I can still take it back out and reform it. This is nothing more than to kinds of putty you need together to form a different color putty that never hardens.

Good product love how coraline grows fast on it

Used a good amount to adhere my rockwork together and also used a small amount for frags. I let the rock work sit out for 24 hours before putting it in my reef and it was completely solid. Also used super glue with the epoxy. The color is good, just make sure to really work the puddy because I still found some grey streaks in places. A little pricey for plumbers epoxy but it'll look much better once the coralline populates the rocks.

Some of these putty adhesives are too okd and dried out. But you won’t know until you go to use it.

Have always used and will continue to

This product did not work at all and it did not do what it states it will do.
