pico reef pest algae problem challenge

Quick question. I'm sure it has been asked here numerous times before. Will the peroxide kill coraline algae?
 
Yes we see it bleaching and coming back in most cases, its a known sensitive on the list a few pages back buried in all this type!
 
Brian that's a fine method since the HP won't get into the ATS. You will use it to forego the usual dieoff time associated with nutrient stripping...no harm I can see unless you don't post before and after pics of the target rocks lol

That's the currency of this thread man!

I've already linked this thread I think fifteen pages ago but the discussion is growing and in case I missed it, this covers some of the anti peroxide science from a few years ago. I want the good and the bad linked here, test null hypotheses all day long its the only way to validate

This thread here in nanos forum is not scientific, its a collection of repeated anecdotes and I think years from now we will have at least some pro peroxide guided applications to reflect upon, that's my goal.

In the first page we talked about the importance of pics, all other peroxide threads are opinion battles and link trades, we have to step out of that with simple pics or we are just repeating in another forum.

Laugh do you have any updates?

Also, I've been doing some pm work in larger tanks and wanted to kick the info up top to save retyping, this poster spot treated a few rocks but had some left in the display and we were considering whole tank dosing to catch the last batch of gha in inaccessible areas

Hello!
I do not blame you for not wanting to drain and treat a 75! My gallon reef spoils me rotten lol.

Can you pull back up the thread with pics of your tank so we can collect all the experiments in one place, a full tank shot and then a couple close ups of the leftover gha

I'll tell you where I'm heading-a modified whole tank dose I nerdily termed a submerged spot treatment, dosing the actual spots underwater, with the pumps off

Just that brief method of contact before it disperses into the tank will zap gha, once its truly all gone you may or may not have to adjust phosphate levels to stop it, but its highly possible it might only slightly come back like twice a year after eradication and two spot treatments a year on a dime sized spot will maintain it.

So you can see how adding peroxide to the top water requires higher concentrations than actually hitting the patch...pretty simple mod huh

So envision extending even that method even further-slow, pulsed delivery right at the base of the gha patch so it covers the gha slowly as it leaks out into the tank, using ideally a diabetic syringe and needle or secondarily a little plastic doser I put a picture of in the thread last week, you slowly squeeze the peroxide right into the base of the gha

Your sensitive organism is the fire shrimp, nothing else. You inject, leave pumps off 5 mins, turn back on.

Depending on what pics show, we know if you can treat all at once or if you break up the treatments over a few days to lessen the dissolved amounts being mindful of the fire shrimp

Gha is highly sensitive to peroxide this will zap it clean and based on regrowth or actual phosphate testing we can create a better plan for prevention

I have been pretty busy. I tried some in tank spot treatments of a few patches of bryopsis but I didn't use much peroxide. Didn't notice any real die off. I did treat my mag float externally and it seemed to work well. Tank inhabitants all are fine. I will post some updates when I really go at it. I got some containers to make enough water to drain my tank most of the way and hit the bad spots.

Thanks for this Thread

Thanks for this Thread

I just want to thank everyone on this thread and the other threads referenced. I think My tank is turning around finally. Sorry Brandon, did not take pictures.

I have a standard 90 gallon reef ready tank with a sump and refugium. Been running in it's current configuration for about 6 years. DT tank has been running for about 8 years. Used to have a mix of SPS, LPS, mushrooms, and some junk (Xenia and Stag). About 2 years ago I started having a problem with bryopsis or gha. At the time I tried water changes, chemicals, and suggestions I got. Nothing worked. FInally the bryopsis took over killed every corral in my tank. For the last year, I have just had an ugly GHA covered tank with some pretty fish. I basically gave up.

Recently decided to try to get it to look nice again. Found this thread and decided to give H2O2 a try. Since I have nothing left in the tank to worry about, I decided to just dose the entire tank. Been dosing about 60ml a day for 6 days now. The tank looks completely different. Still a little GHA left, but getting smaller and smaller. This stuff really does work. I may have a reef tank again real soon.

Thank
Kev

The treatment:

H2O2 squirted directly onto algae

Saltwater dip to remove remaining hydrogen peroxide

And we wait and see:

More pics to come, as the algae dieoff begins.
 
I did some manual removal of algae as well, in the interest of full disclosure. I couldn't pull off a lot if it, because the birdsnest coral is too sharp.
 
If I could pay for great pics that would dang sure qualify

I noticed you went undiluted, prediction time

Algae dead, sps not affected

Normally for safety we try to dilute those dips, but sps across the board like zoanthids are simply being bulletproof yet we ascribe total must-be sensitivity to sps because they are so challenging to keep in the tank

I bet your straight-on I'm feed up with this stuff external application works fine, some of the algae has denuded a bit of sps tissue but if kept carefully it will grow back.

Really thanks for posting banker

No problem Brandon.

I didn't fully submerge the colony in peroxide, just squirted the offending areas good and proper, so the SPS flesh wasn't exposed to more peroxide than needed. The colony already looked like crap, and someone else has had good luck with seriatopora.
 
Alright as promised here is the nuke results. Sorry it took so long I've been rebuilding my return pump due to a leak (prior to and unrelated to the nuke ) and setting up a new reef for the wife. These are all before shots. Notice the cyno on the flower pot and the nasty algae in the mushroom corner as well as Neomeris on the pumps and in the sandbed. This is 125 gal ( maintank, sump, and 40gal refugium ) true water volume setup. I dropped 5-16oz bottles of 35% H2O2 and let it run system wide for about an hour, all against the advise of Brandon but as a result of my loss of patience after fighting this issue for almost 2 years:headwally: after the hour run I did a 120 gal full drain and refill with fresh seawater from my LFS

This is all in, Skimmer off and GFO removed. The water fizzed up like a bottle of 7up! Instantly lost fireworms by the hundreds and cyno. Down side after about 20 min I lost it all!:facepalm: every fish, every crab, my banded coral shrimp, copepods, amphipods, and isopods. Flowerpot, mushrooms, zoa's, chalices, LPS and SPS closed up pretty quick and my Rose annenome isn't too happy at all
