EcoTech Marine Coral Glue Gel is an adhesive that works great underwater, being ideal for aquarium repairs, attaching coral frags and sculpting live rock. It is long lasting and it bonds very easily, ensuring fast results with little mess. It can be used to glue corals upside down. It only takes 10 seconds for the glue to set and 5 minutes for it to cure. It has a long shelf life of 2 years and it is equipped with a pin-cap which prevents clogging. The gel has been triple distilled in order to ensure purity and that it is pH neutral so it does not have an effect on the tank. The small 30 ml bottle is perfect for little touch-ups or minor repairs.
Before use, it should be made sure that the in-tank flow is off. The glue can be applied to rock and coral both above and under water. It is completely safe so do not hesitate to use generous amounts of glue in order to provide a solid support structure. Hold the item in place and allow the glue to set until it becomes stable. Allow some time to pass in order to make sure that the glue has hardened and cured properly before turning the flow back on.
