Removing sand/crushed coral bed???

[stoneriff]

I currently have about 4 inches of gravel in my 120 mixed reef. If I remove half my gravel bed, can I cause any problems?

how old is the tank? if its established, your wiping out a major amount of essential bacteria

I would start with vacuuming the sand/ gravel 1st and see if that helps. Do about a square foot every Water change. If you go with removing the sand, do it over a few days. not all at once.

You don't want to be digging into a 4 inch sand bed, at all. The bottom layers contain hydrogen sulfide, and will kill most everything.

You must remove all animals first.

I appreciate the advice.
