Frags back from death. Tank Algea. To stay dirty or not

[chicago]

So here are some pics of my rock in the DT and my frags in the DT that have be sitting and waiting to come back. Frags came back from literally death. Tank is looking dirty.. algea on rock and actually grown and covering the gravel.. OF Course nitrate and phosphate are reading zero as most likely being used to fuel all the growth.. I am thinking to slowly use GFO to help with the algea outbreak.

Here are some pics.

Here is a pic from months ago and you can see the algea is not growing on the frags and the rock.. but there is some starting on the gravel.. I was using more GFO back then... and the lights in back of the tank were not on.

Leave things be. If they’re on the rebound, that’s good. Just clean up the algae that bugs you but don’t go using any method that got you there in the first place.

that looks like cyano , I would dose a cap of H202 everyday , it will clear up , just dose it in flow like your sump or overflow
