With Aquascape putty, along with most if not all two part epoxy products sold in the aquarium trade, it is important not to over work the product under water.

When manipulated underwater the talk fillers that give the product its putty like consistency can be released into the water. This itself is not toxic, as with the other components of the putty. However it can cause a reduction to the oxygen levels available to the inhabitants in the same way that adding unwashed coral sand to the aquarium can.

It is also important that circulation pumps are not pointed at the putty until it has set. This is for two reasons, the item that you are trying to attach may be pushed loose by the flow of the water and it will give a similar result as overworking the product underwater.

If the aquarium water starts to cloud when you are using a two part epoxy stop use immediately, make sure that the water is well aerated, make sure your protein skimmer is working and wait for the water to clear before continuing. If the water has become very cloudy a water change can also be performed. If you are using a large amount of Aquascape in a populated aquarium it is best to do parts at a time and not all at once.

Epoxy putty’s are not glues, some support may have to be given as the putty hardens if the item being attached will not stay in position by itself. This can be done by propping it in place with another piece of rock, acrylic rod or even a well positioned aquarium scraper can sometimes do the trick.

There are over 250,000 sticks of Aquascape alone used every year and remains one of the most popular products on the market for attaching rocks together and keeping corals/frags in place.
