These LED's just aren't cutting it. Or - are they?

Phosphate and nitrate are too high.

Nitrate should at at 0.
Phosphate at 0.02 or less.

ah come on - too easy. My nano tank has higher amounts of both. I run both gfo and carbon, with a fuge crammed full of chaeto and macro algae.

I was never that impressed with the Vertex fixture. When you say corals are declining, what do you mean? Are they bleaching or browning?

[neoh]

hammers bleached, but are coming back - slowly. No growth, nothing fully extending, zoas are melting over time.

sounds like too much light

[Slyguy00]

Id agree. My corals have never been happier since switching to led

[Saltnoob]

i have the sunbrite led and it is amazing i dont know my light is about 5 inches fron water top and everything is great i got a goni that is about the size of a basketball and polyps extend like 7 inches it loves my led

My nitrates are at 20 ppm and phosphates at .26 and everything grow like weeds. My SPS grow much faster than some people who have low nutrient system. I do feed my corals quite a bit, zeovit amino acid, coral vitalizer and sponge power each day, fauna marin ultraclam, ultra zoa and ultra min 3 to 4 times per week.


Colors are great too. I am trying to lower this a bit but was told if it's not broken don't fix it, so I put some bio-cube to lower the nitrates slowly and it seem to be working, nitrates are at 5ppm.

At some point my nitrates were at 50ppm and more, phosphates at .36, no problem with that either.

daniella3d, thank you for your input.

The corals seem to be acclimating a lot better to turning up the whites. I took a picture this evening:
