Hi all ,

I have a 30cm cube set up 3 months ago with Chihiros C2 rgb running for 6hrs with 30mins ramp time. I am struggling with algae’s I cannot identify. There are two types of algae mainly green type coating the leaves of Pinnatifidia mainly and black/brown hairy kind on hair grass. Any idea Wat types are these and how to fix it.

Hi all,

A bit difficult to see but it look like they might be <"filamentous diatoms"> (<"Fragilaria / Synedra">) on the Eleocharis (Hair-grass). I'm not sure I can see anything on the Hygrophila leaves, but the photo shows some iron (Fe) deficiency symptoms on the ?Rotala, under the light reflection.

Hi all,
I believe these are Rotala Ceylon and this this their form?
Not a plant I've grown unfortunately, but I can see from the images it naturally has pale new leaves.

Just keep an eye on them, if they look very pale (rather than just pale pink) or get noticeably paler then it maybe an iron (Fe) issue. Have a look at <"Duckweed Index says Nitrogen please?">.

cheers Darrel
