How to use:
Put the ISTA Solid Glue into hot water around 50 Degrees Celsius/120Degrees Fahrenheit (do not use with over-heated water). The glue will change from white to clear. When the color changes, you can form the glue into any shape and use to bond the corals and hard-scapes. When the glue cools down, it will turn white again. It takes about 10-15 minutes. If necessary, you can reheat and reuse the ISTA Solid Glue as many times as you need to.
