Welcome! Glad you joined. As you get your nitrates and phosphates under control in your new tank, that hair algae should naturally become more controlled. What I use in the meantime is this little scrubber - during water changes I take rocks out, scrub with flexible scrubber, rinse with water that was getting thrown out anyhow, and put the rock (minus algae) back in tank. Superglue holds the scrub brush bristles into a bit of spare tubing that forms a nice handle.
Have you considered starting your build thread? I found its a great place to document my tank's evolution for myself. I started tank first then joined, so I'm still finding myself going back collecting pictures & updating historically as well as current state. Once you create your first post in your thread under Forum > Member Aquariums and link it to your account, they will give you build badge (look left, under my ID)
