Today we did a massive clean up of the sides of the tank. The previous owners had allowed a large build up of coral, salt, etc on all sides of the tank. We did the front when we first got it and we did a more thorough cleaning today, including the back. Now I'm wondering if that could cause a spike in nitrates with all the gunk we stirred up? I'm planning on a water change tomorrow, I was only going to do 10%, should I plan on more? Is there anything else that can be done when the nitrates spike, besides a water change or is it just a ride it out type of thing?
