سيكيم كورال كريت

Mixing the two parts was stiffer than I expected, but once I kneaded it for a minute it bonded my frags to the rockwork instantly. Left it alone overnight and the base is rock-solid now.

Mixed a batch of this putty and was impressed how pliable it stays for about five minutes, giving me time to position a frag exactly where I wanted it. Cured rock-solid within a few hours underwater without clouding the tank.

Used this to fuse two pieces of live rock together for a more stable arch, and it set rock-hard underwater in about 15 minutes. The putty is easy to knead and shape, and my frags haven't budged.
