I have a dead crab in the back sump of my DT, it’s fallen down the chamber the skimmer is in and gone under into the second chanmber laying beneath my mechanical filtration, will I have to pull my sump apart to remove it or should it be okay to decay naturally, I have seachem prime I could use if ammonia builds up? I’m scared it will wipe my tank as I’m fairly new to reefing; anyone got an opinion? ( sorry if this isn’t an emergency )
