The above photo showcases the latest iteration of my saltwater display tank. After discovering the disintegration of volcanic rock on the sand bed, I replaced them with pre-cured Indonesian live rock. I purchased 2 of them for a total weight of 7.5 pounds for my 10-gallon tank. Since then, my fishes seemed much happier, cruising around the crevices of the rockwork and munching on some new algae on the rock surface. I even witnesssed the ocellaris clownfish resting on top of the larger green chromis in midwater. The last addition I made was a plug-in timer to control a daily artificial sunrise at 08:30 and sunset at 18:30.
