Tangs, rabbit fish, lawnmower blenny, lettuce sea slugs, emerald crabs and pin cushion urchins are some species that may touch this stuff from what I have read. Issue is either A) I cannot have some of these in my tank. B) As Reefing says, it grows fast so I would need a lot of them in hopes they eat it all. or C) Its up to the individual animal. Some people say their emerald crabs love it, others say theirs don't touch it.
Looks like the best way is to uses Kents Tech M as it has a special additive that will kill it.
I assume I could add my clowns now as people do the Kent treatment with corals and fish. But since I only have a CUC I don't think I would add the clowns now if the high Mg would bother them as its not worth it since they are happy in the QT.
Also, people report tank crashes after raising the Mg. And sometimes it will all appear to be dead but come back later.
There are also tons off different methods with the Kent M. Most seem to agree raise MG by 100ppm per day to about 1600ppm until it dies down. This will take me a few weeks. Then I have to continue WC until Mg is back to normal levels.
So my question is. Since My CUC is my only livestock (and I could even relocate most to the QT), can I raise Mg faster then 100ppm per day? Or will this cause another crash and force another cycle.
Not the best start on my first SW tank :(
*edit* BTW I did a mean haircut on it around 1 am, and let the floss catch the remains. Its pretty bare now, but it will sprout back. The snails were cleaning when I checked this morning, but did not seem to be in areas where this is growing.
