I am in the process of a fallow period and was hoping to really fix up my tank before I start to add fish back into it. I was wondering what everyone’s advice would be for switching substrate from my current to a new either live or dry substrate. I currently just have a bunch of inverts and hermits along with rocks and corals in my tank and was thinking about draining the water and saving some, rinsing the rocks out into the water and really scrub them down. Scooping the substrate out and either just rinising it well or just straining some of the crushcoral I originally added to my tank out. Then adding a new bag of sand. I’d have to rinse the sand now thanks to reading the sand rinsing thread. Just was wondering how possible this is to accomplish in a day with not too much stress to the corals.. I know I will be stressed
