Majanos

[MXC511]

I have a 75G Reef, that is infested with majanos. I have done a lot of reading on the forums, and have found that a lot of people have luck with copper bands and file fish, but there's a risk of them eating corals. I bought the majano wand which works great, if it weren't for having hundreds of them. I also have been using a product from Fosters called aiptasia solution which works great as well, but if it covers or gets on any corals it kills them too. I really just don't know where to go from here. They are on my power heads, my cords, overflows, rock, sand, CORALS. I mean everywhere. The biggest problem is them being on the corals and places where I cant really get to them. Do I just start breaking the tank down and fragging whats salvageable from corals and lose thousands or what? Ive been battling these all summer and I'm at a loss for words anymore. Does anyone have a compact solution or advice on taking care of these at the numbers I have? Especially since its not even the rocks covered with them? I'd REALLY appreciate any input anyone can give me. Thank you so much!

Here's what I do. First, I make a LOT of kalk slurry. Combine 1 part kalk powder, to one part glycerol, to 7-8 parts DI water. Mix vigorously. Also mix prior to each use, as the kalk will settle out. Turn off as much flow in the tank as possible. Basically, have your tank running on minimal flow... in my tank, that means all tunzes and vortechs off... just the return pump stays on, and that is directed to blow back behind the rocks. The idea here is you don't want water movement blowing the slurry away. Apply the kalk slurry with a syringe directly onto the majanos. Completely cover them. This obviously only works for majanos on horizontal surfaces... you'll have to use the wand for trickier locations. Let the kalk sit there overnight. Yes, overnight. Turn on all flow the next morning.

Obviously every tank is different, so if your tank is severely overstocked, or there is some other reason your tank wouldn't do well with flow off for that long, then adjust this protocol as needed. The idea is you want that kalk to sit on the majanos as long as possible.

Repeat this process religiously every week, even on locations where you can't "see" the majanos anymore.

I usually mix up the kalk paste, turn off all flow. Let the kalk paste sit on the spot for about 1/2 hour. Then syphon off all the kalk paste as I do a water change, then turn the flow back on. By syphoning off the kalk paste you don't have it floating around the tank getting other corals.

IME the small amount floating around the tank doesn't hurt any other corals, and the 30 minutes on the majano is insufficient.

Would the kalk paste harm corals? Cause the tank is heavily stocked. And alot of them are touching or in colonys of my corals.

Yes it will harm the corals if you get any of it on them, it's a tricky thing to do unless you have a lot of room to work with, that kalk paste will scorch a coral in a heartbeat, be very careful.

I would go ahead and try a matted filefish. Mine is an aptasia ,monster and I assume it would be the same with mojanoes though I don't know. Plus, its a great fish. Very cool and fun to watch. Always out and showing off its spike.

Also, the infestation is likely due to a nutrient imbalance within this system. I recommend massive water changes and perhaps a change in bioload.
