I have a new frag only system I just set up. It's a 90 gallon 72"x24"12" with tons of rock and a bubble king mini 180 skimmer. I have the whole system cycled and ready to go. Now that I look at I i'm questioning if I should have put sand in the tank. the only reason I was thinking about doing it was you can stick frag plugs in the sand therefore increasing the capacity of my tank. I'm going to be keeping mostly SPS and some Chalices and Acans. What would you guys do? also how hard is it to add the sand with water already in the tank if I do go that route?
