8 Week old saltwater tank -White Stringy bits

[DJBlacklight]

I have about 8 week old 160L Saltwater tank with my cleanup crew, about 5 turbo snails and 2 blue legged hermits and added 2 clownfish about 2 weeks ago. All is going good so far. Over the past week some white stringy stuff is appearing attached to the rocks I have in there. Is this Algae and should I remove it with a brush or just leave it ?

You can siphon it out. Whether it's algae, bacteria, or something else, siphoning it won't hurt anything.
