I will be using conditioned tap water for my 10g FOWLR. I know I run the risk of battling algae, so what critters should I get to fight it if it does become a problem.

Nope. I have fine sand in my fuge and I have 2 very small nassarius that do just fine. Hermits would be fine. Overtime it seems that the fine sand gets a little packed if it is in a low flow area, in a DT it tends to get blown around depending on your flow rate in the DT. I would absolutely stay away from sand sifting stars or sand dollars.
