barebottoms in Freshwater make sense to me but in Saltwater it doesn't quite fit. There is just too much going on in the sandbed to not have it. I'd really like to see the levels in a BB saltwater tank. If you are worried about nitrate and algae issues it's the quality of the water. If you're using RO
water you really shouldn't have any algae problems because you're absolutely eliminating algae's principle food source. If you have a good clean-up crew, don't overstock, and don't overfeed, then you won't have any nitrate issues. Without a good sandbed you won't have any nitrates at all because you'll just be stuck with ammonia.
Also I believe the current poll results support my position. BB just isn't an option for SW
unless your sand is in your sump.
