Help with Coral

[Ginu]

Flow is good, I would worry more about the parameters and it also looks like the tank is quite new so its not established. How old are the rocks? They seem to be dry rocks as they are lacking coraline and you have virtually no algae which would indicate the tank going through different stages also known as the "new tank syndrome"

I found when my Mag was low, some corals like anemone's would get huge... which in some ways is cool as it would typically split which I was ok with and then some corals like leathers and trees would get really ticked off and shed which gave me a new problem to deal with as it would **** off the SPS causing a chemical war (ended up killing all my SPS)... and i think thats why its recommended not to mix softies and sps...
The good part is, once you get the Magnesium to the desired level, you will only need to treat your WC water to match the display.


Now that I've changed my tank around and running a ULNS with full blown zeovit and dead on parameters, the same anemone shrunk from baseball-handball size to smaller than a ping pong ball...

If you will attempt to raise the Mg I recomend raising it by 50-75 every day(max 100)

What salt you use? typically all salts are low in Mg and the reason I asked whats your Mg at is due to your other post asking about the health of the anemone which I think might be stress caused by the low
Mag....

Also anemone's do well in more established tanks and I believe your tank is about three months which is young, so you might have troubles with the it for quite some time.

Keep in mind different corals like different water parameters.
