GHA... what is the source??

[jarviz]

I just started getting some GHA on my tank. I tested about 5-10ppm nitrates and 0.08 phosphates. is that enough to spur algae growth? i mean i thought these numbers would be low enough to prevent them from starting lo. i guess not?

No...but those are good numbers. Too low and risk you other organisms out competing algae - like dino's - trust me...GHA is your friend compared to those. A little GHA is just your tank saying it's balanced in your favor....for now.

dang i really thought if numbers were low enough i could prevent most algae .while keeping my corals happy. Guess there's really no such thing as an algae free tank without risk of dinos/cyano.

Oh I think after a long maturing process (at least several months) you can have enough coral growth and micro fauna to almost eliminate most "visible" algae. But algae is always going to be present.
