Having an absolute nightmare with ...

[Sid996]

Hi

I'm having an absolute nightmare with this dark purple/red algae.

I can clean rocks within 48 hours they are covered again

Doesn't seem to bother the livestock, tested parameters they all seem in check.

Any ideas how to finally beat It


Cheers

It looks like the beginning of cyanobacteria. My first question is if you have any powerheads in the tank? The water looks a little cloudy, I would run some activated carbon to try to clear it out. Cyano is generally caused by excess nutrients and docs and low flow. Water changes and manual removal should help
