Hi everyone. I have a 60 gallon reef tank that needs a new sandbed and major cleaning. I was wondering if anyone had any advice on procedures and the effects while doing this. I really don't want to kill anything if possible. thanks
Well you could do it in sections so that the bacteria isn't all disturbed at once. I would expect you are going to have mini cycles when you start moving stuff around. Depending on the dimensions of the tank, you could divide into halves or thirds and replace the sand in each section and waiting a month or 2 in between.
