Recommended Posts

hi, what are these that are growing on my macroalage?

been growing recently and when i tried to scratch it off, they look like dirt?

harmful? or can just leave them as they are?

however, realise that sometimes they do rise up to the water surface, forming a silk-like layer

thanz

It's cyanobacteria. The dissolved organics (DOC) is too high in your water.

Try as hard as you can to remove it physcially, they will come right back, fast. The only way is to increase skimming or decrease the bioload of the tank. Try feeding less to start with. The more radical way is to add iron to increase macroalgae growth such that it outcompetes the cyanobacteria but that could cause a hiar algae bloom instead.

I had those in my tank during the first 1-2 months of my tank. Now no more and I kind of miss them. I think the amphipods rather enjoy eating those...everytime I manually removed clumps of these....I would surely pick up an amphipod or two..

Btw..smell them..they smell just like fresh seafood. :D

Always something more important than fish.
