Well BJD is a disturbing pain that on the other side is a warning sign.
Here is what you do to cure it quickly since it can stop as quick as it comes ;-)
First at all it's a bacterial infection that affects corals that are not truly happy in your tank.
I did have this always in the past after feeding wild & fresh oyster, so I stopped using fresh oyster, lol.
Since it affected larger colonies that I could not get out of the tank I had to treat it on the tank.
Anyways, the worse things is to pour medications in, as we all know.
Since it's bacteria, it loves warm temps and hates cold temps.
So dropping temp down to 24/25 degree C is what typically reduces the growth time very effective. Just for a few days.
Then you keep siphoning the brown slime away 2 times a day with a lil RODI hose and trash that water, that stuff is easy to remove.
Don't blow it away with the power heads !!!!
Complicated Montis where you can't suck the jelly away for example, break off carefully and trash it.
When you do the siphoning a second time a day, just siphon along the new jelly line that grew back much slower due to lower temperature, you will see that corals start to recover, jelly stops growing or at least doesn't grow that fast anymore.
Siphon as much as you can and keep the lights off on the first day, dimmed on the second day and see if there is jelly coming back.
Typically I got rid of the jelly on the second or third day then.
However, the dosing and application of Microbacter 7 helps significantly to compete out this bacteria during this time, but don't overdose, just support.
Otherwise the nutrient levels will fluctuate and further stress the corals.
The Jelly is a sign that the corals are not really that healthy and their immune system is not ideal.
Try to keep all basic parameter in check and stable. Give it a good portion of live food such as Phyto and Oyster feast with some Selcon for some vitamins in the nighttime.
Cheers,
