Aquaforest StoneFix 6000g
Quickly bonding glue based on cement. Best for joining large elements of live or ceramic rock. It does not contain toxic compounds which makes it 100% safe for fish and invertebrates.
Method of use: small amount of glue should be mixed with water until homogeneous, plastic consistency. Start linking the elements immediately. Dry linking is recommended. In case linking under water is necessary, switch off all circulatory and shunt pumps, link individual elements and leave for bonding for 15 minutes. Temporary water blushing will not be harmful. For large percentage of plants in aquarium, linking of no more than 2-3 elements a day is recommended as the sediment might slightly elevate the water pH in aquarium.
