Is it safe to perform a 75% water change for an aquarium containing ONLY already cured live rock and sand?
I ask because the current water is tap water, and I recently installed an RO/DI system. There is alot of brown algae on my glass, which doesn't scrape off easily so I was going to do a thorough cleaning and ensure the "bad" water was flushed out.
