Alge issue. New tank or issue

[Gordon15]

This green alge is everywhere. It’s surface alge. Tank is 6 months old. Is this just part of the cycle? It was brown the. Went away. I cut feeding and lights down a ton but two weeks later no change. Leave it and wait it out or take action?

I attached my levels below and pic of the alge.

You haven't built up enough good nutrifying bacteria.... the whiteness of your rock is a testament to that.

After six months? Not part of the cycle. With nitrates at zero this is probably an underlying cause.

Phosphate slightly elevated ( you want < .04). Reduce white light intensity and add some cleaner snails such as :
astrea
cerith
nerite
Turbo

Is tank at or near a window?

Not near a window. I’m testing with Salifert kits. Kinda hard to read those at times.

Nitrates are around 10PPM typo. Nitrite is 0
