I'm rebuilding a 180G tank that's been offline for over 10 years (major tank disaster I couldn't afford to fix). I have had the sand and formerly-live rock sitting dry in trash barrels in the basement all that time. I cleaned off the junk from the sand and brushed off the rock, then put them in the tank. I've started a fishless cycle and things are going OK.
But I have something growing in the tank I didn't put there (intentionally). The sand is acquiring quite a lot of these little blobs. They're pinhead-sized or smaller, and under tank lighting they are pinker than they appear in these photos. They look almost like pink grains of sand. They're completely uniform with no differentiation. They're very soft and break up easily when poked with a probe. The smallest divisions on that ruler are 0.5mm. Any ideas what they are? They certainly did an impressive job surviving that long!
