hi, my puffer sifts my 1.5 in deep crushed coral bed constantly. there was so many macro critters, they were in the 10s per square inch in the entire aquarium. after about a week of the puffer and dwarf lion being back,, they are not visible at all! so my question is.... do you think i need to switch my sump from rubble to sand bed? i chose rubble for simplicity and ease of moving. thanx Dale.
