Green algae

[Silam1984]

Hi all had green algae forming on my base rock an tried brushing it off but it won't come off any ideas on the best way to get rid of it?

Is it hard? Could be green coraline algae. It comes in many colors, not just purple.

It looks hard I tried scrubing it with a brush and it did nothing I'm just worried if it'll harm my fish and shrimp my snails don't seem to be eating it either

I bought some base rock that did that exact thing a couple of days after adding it to the tank. It ended up just dissapearing a week or so later and became purple...

Just keep an eye on it.

To me that`s the begining of coralline algea. It will turn another color in a while provided youe water parameters are ok.
