I am struggling at the moment to keep all my SPS healthy.
There as been a steady decline recently in the overall health of some of my SPS

And i am struggling to find out the problem.

Tested the water

nitrate .10

PH 8.4

KH 10

Calcium 410

Doing 75 litres a week water changes. Using SERA salt.

Currently +- R6000 worth of SPS i could lose.

Please any ideas will be appreciated.:41:

I am currently thinking it could be a toxin or even a hitchhiker :014:

Are they very high up against lights or just moved up, or new to the system from a lower light system.

Sounds like burning, do you have pics.

To answer you're lighting question Makaeel.

The tank the corals came from had more light than my tank.

The corals are not getting to much light.

So zi plot thickenz.

flow can b very deceptive. make sure there is sufficient flow on that coral. water tends to make some "dead-spot", even in high flow tanks. in my case i turned on of my pumps to blow more directly on this frag with better results

Can we get any pics of the actal bad spots, It could be crabs, they can shave a coral right down to the skeleton, removing all polyps.
