kno3 dosing and algae blooming

[jccaclimber]

I got myself in a similar situation with nuisance algae, which I'm still slowly digging myself out of. In my case my macro crashed, and things went downhill from there. Mine may have been very low K, although the undetectable NO3 for a long period of time didn't help. In any case each and every attempt to starve the algae has been met with pale dying coral. I finally decided to just put on a dosing pump with KNO3. The nuisance algae is still trying to take over the world and requiring some heavy manual removal, but the corals are winning and the macro is growing again. I figure if I keep this up long enough the nuisance algae will give up (it is weakening).

My point being that starving algae has never been a successful venture for me. Focusing on the health of the coral and macro and letting the nuisance algae eventually lose has been successful in a few different systems.

thank you so much for your post!
im starting to get the same conclusion as you did and right now i'm really only focusing on my corals health and well being. in a matter of fact, the green algae on the bottom of my tank grown pretty nicely and created a nice like grass layer. kinda beautiful actually. its also causing all the algae on the walls and rocks to disappear slowly. ill guess time is the best medicine for this case.
i'll keep updating on the tanks progress.

I know what you mean about nice green grass. Having also kept freshwater moss tanks, every time I see bryopsis taking over the world I remember that I went to a lot of trouble to make freshwater tanks look pretty much like that. That said, I would stay on top of that nice layer of grass. It has a way of spreading out of control, so the sooner you can get rid of it the better, just don't sacrifice the health of your livestock to do so.
