How long does it take to kill coral?

[fish farmer]

I've been using F Aptasia from Frank's Tanks(sponser on this forum) to keep mushrooms from taking over real estate I'm saving for some sps in the future. This stuff will kill off patches of coralline so be wary of where it lands.

I siphon out loose mushrooms monthly as well as cutting back other softies, and would love to give them away to locals, but most locals I know don't desire ugly brown weed corals.

rcpalmer1 - I'm with you on this. Sad to see the kind of responses this evoked, this is typically absent on R2R and that's one of the reasons I like prefer the site over that other one. I see absolutely no fault in trying to target and eliminate specific organisms, especially those that have become a pest and are threatening their neighbors.

Back to the topic at hand, from my past experience, most hard corals are toast in a couple days if there is truly zero water flow. I've had corals land upside down in sand on several occasions, and they don't normally last more than a day or two if I don't catch it. So I'd wait 3-4 days and check. If this doesn't work, is the rock one that you can remove from the water for a few minutes? If so, there are other options. Something that worked for me immediately was application of straight muriatic acid with a paint brush (and dip the rock in a bucket of salt water before returning it to the tank).

I would have to tear down my whole aquascape.

I believe killing off corals is mean. I’ve had 3 heads of aptasia and I absolutely HATED killing them off. I grow pods to feed my fish. I eat animals. I contribute to a hobby that takes animals from the wild for my viewing pleasure. I am not stupid. I see the hypocrisy. This thread is breaking my heart. You’re doing the right thing. But that doesn’t make it easy for me to swallow. So I’ll leave u with this piece of advise and wish you well before I unfollow this thread:

Try squirting them w boiling hot fresh water a few times a day. In a large system, the heat shouldn’t have enough of an impact on the temp of the tank to cause anyone else harm.

Good luck and goodbye

Here you can see one of the small corals that got killed. here are some that I moved to the bottom.
Here is what I have done.

Thank you for the people who posted this morning . I was really getting disappointed with R2R.

Agree that people are being a bit too sensative about this.
I would of used kalk paste personally make it thick enough and it will burn the coral and kill it, almost like being stung by a coral.

I normally just go in with a table knife and chip away, takes a lot of time but at least you can sell the frags and make some money.

Pavona are very Hardy and can die off and literally come back from nothing from my experience, so good luck with that one.

Lesson to be learnt here though when buying lps don't put them near sps.

I went back and reread your original post- I misunderstood it! I'm sorry for jumping down your throat. In simple cases of overgrowth and coral warfare, I have no problems with what you're doing. I thought your intentions were different. My bad! No hard feelings? Also, I agree with the advice of the others- some thick kalk paste might just do the trick.

Well I can safely say it takes more than 3 week of no light. I had my acro next to the plastic start growing around the ziptie. The coral underneath are pale but still have color. I am going to rewrap for another month and maybe by then I can find a deal on a homewrecker.
