What sand for remote DSB

[TheReefGeek]

Yes, aragonite is a better choice, but more expensive. For a Remote DSB, many people already have an aragonite sand bed in their display tank. Silicate leeching is what may cause diatom and other algae blooms, but this is apparantly somewhat of a myth according to a large thread on RC. I would still monitor using a silicate test kit to be sure.
