I purchased my tank used from a lady who had it set up by a well respected local company. In the sump they employed a refugium section with a deep sand bed. This makes me nervous because sometimes the flow moves the sand around and just because I am in general a worrier and deep sand beds seem like they can be a problem down the road. I would like to use miracle mud in my refugium.
How would I go about removing the deep sand bed without risking a nitrate/ammonia spike? Should I just leave it alone? If I am going to just leave it alone should I disturb small areas of it every week or two to keep it from building up any surprises?
Thanks for any info
