I have a 10 gallon with bryopsis algae in the beginning and I was told to add magnesium to kill it and it worked. I also started adding GFO
to remove phosphate in my tank. I also tested my water it has low nitrite.
Now my tank have green hair algae on rocks and glass. Should I just restart the tank? what should i do? the magnesium doesnt seem to work on green hair algae.
