Hi, Sam.

It's a very light dusting of diatoms. I wouldn't worry, it'll get worse before it gets better most likely. As the tank matures, it'll become less likely to see an outbreak. If you keep nutrients low so you're removing the food diatoms feed off, it'll make it hard for it to stick around.

Also some clean up crew will turn the sand bed over, keeping it white. If nothing is turning it over, it'll go dark overtime anyway as it'll get the same type of algae you have to clean off your glass on it.

Both Nassarius snails, and super tongan nassarius snails work through the substrate. The bigger super tongan variety do a better job of churning the sand bed, but the little regular nass snails breed well in tanks and so you could end up with quite a few of them doing a decent job.

Nass snails are doing a great job in my tank.  They hide away in the sand, with their little siphons poking up like snorkels, then when you add some food they come rumbling up like the undead  :D

Conch are great!  Everyone comments on their 'elephant's trunks' when they see them, and how they seem to jump/lurch forward as they move about.

The SSSF will probably need supplementary feeding.  Bury a bit of a raw prawn or raw fish for it every week, and it'll sniff it out.

Yeah the SSSF was a bad idea, that's why I didn't suggest it. It'll certainly perish.

Agreed. Conch's are ace...like a little vacuum hoovering the sand. The kids call ours "noo noo" ....

+1 to this, we have 4 adults and about a million tiny baby ones roaming about lol. Who needs fish when you can have a tank full of snails lol
