algae

[brotherd]

My tank is still cycling but this has shown up on a couple of rocks.If it's bryopsis what do I do about it? It's green,feathery and sways easily in the currents.

If you say it's feathery...good chance it is. Are you able to remove the rock and clean it outside the tank?

Crappy pic I know but def feathery.I can remove the affected rocks if need be.

At the start I had a small rock with that...I took it out and gave it the acid treatment. Now the rock is nice and happy and back in the tank.

Hair algae! Cut your lights, they dont need to be on during the cycle. This is normal, don't stress too much about it.

Acid? No lights? Would vinegar and a toothbrush work? If I turned out the lights how would I stare at the big box o water? I tried to pull some off with my fingers but ended up losing some in the tank.Oops.

What are your params at? You could add your cuc if it's done cycling!

Just cut the lights for a few days. I threw a couple of rocks in my 180 that were covered and my tangs devoured it!!

Using acid is a final approach to remove this unwanted algae 100%. I used muriatic acid and it works like a charm. If you were to go this route i'll give you needed info on how to do this safely.

Vinegar won't do a thing...just kinda whacking an elephant in the ass...it won't move.
