In the pic is just one rock. My tank is completely almost over run with this.
I attempted to try total darkness for 48 hours. And all that seem to do was make my corals mad.
Tank is about 7-8 months old.
Calcium is @ 400ppm
Gh is @ 10, 179ppm
Phosphates @ less then 0.25
Ph @ 7.8
Ammonia @ 0.25
Nitrite @ 0ppm
Nitrate @ less then 5.0 it's more yellow but not the same as the card.
And I just did a big 20 gallon water change on sat. And put a phosphate sponge in and also run gfo and carbon.
It's a 55 gallon tank with a 35 gallon sump.
