I am going to change out my crushed coral for sand. So that I don't go through an ammonia spike, I am going to take all my crushed coral and put it in those cheap plastic rubbermaid food containers and drill/puncture little holes in them to keep the water flowing in and out and place them, temporarily, on top of the new sand bed to seed the sand, and then after a few weeks or longer (what do you guys think) remove the plastic containers and have just the sand bed. Ideally the holes would be large enough that any critters could make their way out, but not so large as the crushed coral will fall through. This allows for complete removal of the crushed coral. but keep the bacteria/critters available to seed the new sand.
Secondly, I just removed my bioballs from my sump. Can I replace the bioballs with smaller containers with holes in them and keep the crushed coral, with bacteria in the trickle chamber? I figure my prefilter, protein skimmer, and then fitler media would keep all the miscellenious waste products, and the water would trickle through the crushed coral (in the conatianers) to be pumped back up to the tank.
What do you guys think?
