Algae problems, please help.

[Kryptonian89]

Hello guys,

I hope this is the correct place to ask this.
I have a big problem with algae on my tank.
I’ve been using excel for a while and I’m not sure if it is causing it or something else.

I notice some small green strings floating on the water column.

I hope you can help me as I don’t know how to deal with it.

Blue green algae and staghorn algae. Increase water flow, more or larger water changes, add more plants and wait for them to establish. They will out compete the algae.

A warningfor you here. Don't siphon water by mouth if you are. Blue green algae can be harmful or deadly if you happen to ingest any.

Thank you very much, goatnad.
I have increased the water flow of my filter to 100% it’s capacity.

Also I have planted dwarf hairgrass.

Now my dwarf hairgrass has algae as well. Is this normal? Should I just let the plant do their job?
