I currently have a 45g, and will be upgrading to a 75 gallon soon, and plan to reuse the sand. Before I transfer the sand, should/can I wash it in a bucket to get rid of all the algae, fish waste, and detritus?
rinse it lightly to get the large clumps of waste out, but not all and not too well. when its too clean you'll get a white cloudy bloom. save some brown water with solids, itll make the water crystal clear.
