Peroxide for dinos: SPS safe?

Well I was free of dinos for around 10 days after a 72 hour blackout, but they are coming back. I dosed peroxide (1mL / 10 gallons) during the blackout as well as changed filter sock daily and ran GFO and carbon during that time.

I'm really starting to lose my patience at this point. Even after the 3 day blackout my parameters were at the normal 1-2 ppm NO3 and 0.05 ppm PO4. I'm thinking about starting peroxide again nightly.

After the blackout some of my SPS was very pale, which was recovered very well since then. I'm hoping that isn't because of the peroxide and an indication that it would eventually kill something. Any thoughts?
 
I once used 2 ml of 3% peroxide for each 50L of water (13 gallons) added it 2 times a day, first before the lights came on, and after they went off.. took me 14 days, and the dino´s were gone.. no sps, lps, clam or anything else took damage.
 
Peroxide to nuke the tank is a bone head way to get rid of them.
Do another two day blackout in a few days
It takes more then once to get rid of them
 
Relativity, why is peroxide a bone head move? I am not a expert but I am pretty sure certain types of dinos don't go away from lights out. I would think using both methods would be fine. At least all my friends had good luck using both for certain types of dinos. Did you have a bad experience with sps and peroxide?
 
Op, for what it's worth I had good luck with random lights off and peroxide in one of our tanks. Only thing I think it ****ed off were some bta's. I dosed the peroxide mourning and night. Even tried a little bit higher dose for a bit.
 
Its volatile your hurting your tank if your killing the dinos with peroxide.

I have used peroxide on my rocks a few times to get ride of algae but when i accendently sprayed it on sps at 3% they died.

Your body makes peroxide to fight off infections and stuff like that but it is highly targeted. It could kill anything living.

THere is a thread of someone who kept dosing it to the tank and his sps all went pale and died. But it took many doses to kill the dinos and it eventually killed his coral not to mention what it does to fish gill. Try inhaling pepper spray

You can get rid of dino with blackout why subject your tank mates to peroxide
 
Many advanced reefers use it to control cyano/dino on full SPS tanks
you dose it in the tank not spray the coral

Hydrogen Peroxide isn't that big a deal its the same as water

It is reactive and that's why you dose low however no residuals to be concerned about ...

Corals actually make H2O2 and use it to feed on prey

"Hydrogen Peroxide isn't that big a deal its the same as water "--not true. Peroxide has an extra oxygen molecule while water has a single oxygen atom bonded to 2 hydrogen atoms. The extra oxygen in peroxide is the reason why peroxide reacts and breaks down organic material. I use peroxide to clean algae on organic gunk on powerheads and circulation pumps. Adding peroxide to your tank water alters the redox potential of the water and the highly reactive oxygen molecules break down organic molecules and destroy bacterial cells. It may work on dinos, but is not guaranteed to be 100% effective. If your tank's filtration is based on bacteria, peroxide may negatively affect the biofilter. I was able to remove Ostreopsis, a dinoflagellate, with aggressive water changes and removal of the slime. This took about a month and there's a small amount still in my tank, but it is not causing a problem. The redox potential of seawater might be an important factor for explaining how dinos become a problem in aquaria. Highly stocked tanks with lots of carbon dioxide and dissolved organic material seem to favor these nuisance algae. Pose your question in the reef chemistry forum to get Randy's educated opinion on this matter. Peroxide is useful when your tank experiences a power outage--adding a small amount to the tank water can provide enough oxygen to keep the animals alive until power is restored. ..............Jim

It's used by reefers who run full AF bacterial driven systems when used properly there's proof there's no ill effects on tank inhabitants i'm no scientist but many people have used it with success....

I used it as a crutch to help keep them from growing out of control between blackouts. It's defiantly not something you use to outright kill dinos, or at least any dinos I have heard of.
OP, have you tried high pH to kill the dinos?

Already dose kalk in my ATO to maintain alk at 8 dKH. I'm only using about 3 tsp/5 gallons so not really near the point of saturation, but if I go up on it my alk starts to rise. Being low nutrient, sps starts to get ****ed off by 10 dKH. My pH runs around 8.1-8.3 during normal lighting cycles, but plummets to 7.9 during blackouts.

This is with a relatively large recirculating skimmer drawing in air from outside and through CO2 media.

Funny I have used it to kill dinoes in a sps system with out issue, I know several others who did it as well. Even with dosing it both morning and night, no corals were harmed, even though I did it over 14 days. Sps corals seemed unaffected by it.

Also I have cleaned several sps corals that were overgrown with algea by dipping them in a half saltwater solution and half 3% peroxide, tried both montipora, acropora and a few different lps with out issue. 10 minutes in that dip dosent seem to harm them.
