Green algae on live sand

[Redrover]

I would cut back time on lighting to 5 / 6hrs
Over feeding...Myself I would feed daily, but a very tiny amount
Weekly water change
Like dogboy said check your parameters...esp.nitrares

[dogboy]

Are you sure your phos. test is working properly? The algae is feeding on something in your water... just a matter of figuring out what it is....

what are your other parameters?

[likwid]

As far as I know the tests are accurate. The algae grows lightly on the glass, which I usually scrape off once or twice a week, but aside from that it only grows on the sand.

RO or tap?

Ro

I was having a little cyano problem. I was using RO(store bought), and I switched to DI and now the cyano is slowly going away.

I would make my lighting period about 5 hours a day.
