I don’t know if I posted this in the right spot but here it goes. Due to a recent epic fail, I nearly wiped out my sps corals. This just so happens to come around a time where I was about to set up a new mixed reef Nano tank. I have decided that this would be a good time to break my main tank down, move the surviving corals over to the new tank temporarily (once cycled) and rejuvenate my current setup. Since the growth of my corals have come to a hault due to the almost wipe out, I thought it would be prime time to fix some things on my main Nano aquarium that has been getting on my nerves (aquascape, wiring, equipment cleaning and lighting upgrade). So now that you know the background, here’s the question. Once everything is removed from the tank, how can I starilize everything including the aquarium? I want to kill everything and anything so that once it’s set back up, it’s a brand new tank again. My main concern is that the aquarium is cell cast acrylic. I don’t want to use anything that will weaken or damage the acrylic. Any thoughts?
