There are many corals with toxins other than palys! Please be careful! Look up gonipora toxin, for example!
I was pretty sure the rock didn’t have any life on it other than the bad algae. See my photo above.
Dont think vibrant will do much However Fluconasal (Flux) may but I rarely trust Flux
Looks like vibrant is just API algae-fix at a lower concentration.
I don’t think Algaefix works against bryopsis. That was my experience. Yours may be different.
This doesn't look like bryopsis though.
Sorry. I didn’t look at the photo close enough.
boiling would be an option, anyway there could be much of live things in it, let alone bacterias, will that cause a nittrate bomb?When I have a rock with problem algae on it, I boil it in tapwater for about half an hour. Kills everything on the rock including the roots. Last time I recommended that though, I was inundated with responses warning me against aerosolizing palytoxin. Fortunately for me, I started my tank using all dry rock and I’m 100% sure there are no Palys in my tank. Boiled rock formally with bryopsis:
You’ll have to use your best judgment. Just assume that everything on that rock is going to be dead, especially bacteria. If you have sufficient nitrification without that rock or rocks you’ll be OK. As far as a nitrate bomb you may see a very, very slight tick up, but I wouldn’t worry about that.
I am thinking how to carry this out as now almost all rocks are occupied by this kind of algae, I need to boil one after another with days of intevals to let bacteria survive, and need to avoid rock kisses rock, tough job;-)
Well there are things you can do to minimize the need for heavy nitrification. Primarily, reduce feeding. I would guess between 1/3 and 1/2 of all the rocks at once for the first shot would be safe if you feed minimally or not at all. Then you could do one at a time or two at a time with the rest of the rocks. Again, use your best judgment. Also, don’t clean anything else like the inside glass or the sand bed until you feel confident that your bacteria has reestablished itself. Algae growth on the inside of your glass in this situation is a good thing.
good suggestion, but I‘d rather replace with new dry rocks under your proposal, seems more safer to me, sure that would cost more, but I really kind of hate those live rocks, doubting they were fetched in some dirty places rather than from caribesea
No. I’ve used it for long periods of time at higher than recommended doses, my tank is packed full of corals and nothing was negatively affected. You do need to keep an eye on nutrient levels as the algae dies, and you need to redose every time you do a water change (the percentage of the original dose relative to the percentage of tank volume you’re changing). You also can’t run carbon for the entire duration and need to take the cup off your skimmer for three days every time you dose it. @dvgyfresh recently used it to get rid of caulerpa in his tank and it worked pretty flawlessly. But to answer your question, other than increased nutrients from the dead algae, there are no side effects. I have seen people say they had problems with their SPS dosing fluconazole, but I’m willing to bet that it is the increased nutrients and not the fluconazole itself.
