My rock work has slowly slid down over the last year and I'm going to take it out and re-do all the rock work, about 300-400lbs. I'm also going to replace about 80-100 gallons of the water, clean out the sump... etc. I'm planning on putting the rocks into ice chests with salt water while I work on the tank. If I don't disturb the sand too much and limit the exposure to air I shouldn't get a cycle right? The tank is a 240+150ish sump.
Anything I should watch for?
