When re-aquascaping the rocks in your aquarium or just moving a couple of things here and there, you will release at least some, if not a lot of detritus into the water that has been trapped in low flow spots and in the sand. The detritus will immediately foul up your water quality, causing a spike in ammonia that will throw off the stability of the aquarium’s nitrogen cycle. When this happens, the corals and fish will start to feel the impact of the very harmful ammonia almost instantly. Because of this, you should have a bucket of water on hand to do a water change in order to remove as much free floating material as possible. These water changes should also be repeated on a daily basis if ammonia is still detectable on your test kits or the animals start looking bad.
