I’ve had my tank running for about a year. About six months ago I lost all my fish due to a power outage and I recently added two Clownfish about a month ago. I’ve had this clearish brown, short hair algae growing on my rock. I can’t seem to get it to go away with water changes. I’ve been testing my water and I’ve had phosphate at 0.1 and nitrate at 0. I’ve tried feeding my fish more to increase the nitrate, but that has not helped. What is the best thing to do to get this algae to go away?

I feel like this pic looks familiar...did you open another thread on this or post about it before?

Manual removal will be the best solution....it will seem like "too much" to do since the algae appears to be covering everything, but take it on in small bits and it will be doable.

"How do you eat a whale? One bite at a time." ;)

Work in 2x2" areas and get the area completely clean. Pluck with your fingertips as much as possible (100% iideally) and place one of your cleanup crew on the cleaned spot when you're done.

Wht is currently in your cleanup crew?

Thank you for your help! I’ve been manually cleaning it and it comes back the next day. Could it be from nitrates or phosphates? I have a few blue leg hermit crab, a tiger conch, and some turbos nails. Any suggestions on what to add?
 
I've had similar stuff like this during new tanks.(6 months to a year) that eventually goes away on its own.

My thinking is keep good flow to prevent organics from settling on the rock, don't over feed to the point some will lay in the rock and sand. If you have corals dosing nitrate directly it's my preferred method to bring it up.

As it weakens over time (hopefully) your clean up crew will start to eat it.
 
A Picture in white lights might be helpful, is that algae green in real life? If algae is growing, then IMO "feeding more to increase nitrates" is really just feeding the algae. When algae grows, its a sign of surplus nutrients, no matter what the test shows IMO
 
It is very simple…algae needs real estate and nutrients: remove the algae manually, add some consumers, keep the aquarium clean with maintenance, add a coral to take the real estate.

Next question? 😀
