Aquascape can be used in fresh water aquariums as well as salt water. The grey colour version was originally introduced for the freshwater aquarium market but both colours will be fine to use.

For larger projects we recommend doing bits at a time and let the sections set fully before continuing. If you try to do too much at once it may result in the first parts being disturbed and not attaching properly. Also it could potentially cause clouding of the water if the wet putty is contiually disturbed, this may reduce oxygen levels in the aquarium.
