hydrogen peroxide

Hi I am struggling to get rid of my cyano. Following twillard’s thread I starting dosing 3% hydrogen peroxide on 10.12.23 at 1ml per 10g (16 ml for my 160 gal). This was making no impact so upped it to 30ml on the 20th. Today there is still little impact. Some matts are lifting up but soon get...

Fauna Marin has come up with a new expensive coral dip called "cili dip". If you look at this PDF, the concentrations suggested for different coral species are identical to those suggested by Justin Credabel for Hydrogen peroxide. You can find his research summarised here. Frankly, this looks...

Hello all, I am new to reef2reef. I set up a 20g tank a couple of months ago. It has a yellow tail damsel, clownfish and flame hawk fish. They are all about 1.5-2 inches long and get along pretty well. The damsel gets upset when the clownfish goes near his rocks but everyone generally gets...

Just got ich/velvet so planning 90 day fallow. I'm fine with QT fishes and inverts but think I can't be patient enough for qt for coral frag swaps. Hydrogen peroxide has been used as coral dips for algae so I am wondering anyone used it to bypass frag quarantine assuming the chemically violent...

My tank has ich, I'm currently practicing ich management as going fallow for 76 days failed (possibly because I'd added corals during that time). My question is, I've bred berghia to clear up my aiptasia... can I safely give some berghia babies away if I did some type of SW rinse on them first...

I have some GSP discs that recently have been hit with different types of algae. While I battle the underlying problem, I'd like to try to clean these discs so the GSP has some room to grow. First I will take a toothbrush to them. Then I was thinking about trying a dip. Hydrogen Peroxide seems...

I used it recently to help fight back against cyano, and I see it being used quite often to help with algae. How does it work? Why does it kill the bad stuff, but the tank seems to be perfectly fine? Why is the good bacteria spared? How is it affecting the inverts? Does it accumulate and need...

Hi! So I'm researching trying to do a copper QT for new fish moving forward (using copper power). I had a couple questions to get clarifications on, and then after that I'll probably make a post sharing my QT plan, just to run it by some pros on here and check for flaws. 1. Could you go 14...

I need to clean a rock out of water since it's full of GHA and I estimate it will take about 30 minutes to scrape it all off, spray H2O2, let it sit, then rinse with SW. I also have a mushroom on this rock but since it's on the lower part I can keep it submerged. Also, is spraying H2O2 really...

So some brief backstory here, I set up my first saltwater tank about 6 weeks ago, got it cycled and added my first fish last week (firefish goby). I decided to forgo QT for the first fish fully aware of the potential consequences of this, figuring I'd get lucky with my first fish and I'd get my...

So i’ve seen plenty of different methods to use H.P. to kill GHA The one that works best for me in to apply 1ml of 3% H.P. onto the GHA on my rocks (since they’re too big and have too many corals to just be taken out) My question is: can i use the one found at drugstores? Or do i have to go...

Hi there, First time poster, long time observer and thread reader. Looking for some guidance to help my father with his 400 gallon Fish Only tank. He has been dealing with an Ich outbreak for a couple of months now and has until now been just using Ruby Reef Rally pro and Kick-Ich in tandem...

I can't find food grade anything where I live because food-grade isn't a thing here. I found a good source of hydrogen peroxide 3% that contains sodium pyrophosphate. I'd imagine the sodium pyrophosphate acts as a stabilizer, and should be present at about 25 – 250 mg/L. Is this amount of...

Hello fellow saltiness, I know barley straw is used as an algae inhibitor in freshwater (especially ponds) because it releases H202. 3% hydrogen peroxide dosing is also used in saltwater for the same purpose. Has anyone tried barley in a mesh bag in saltwater or are there other things released...

Over the last month or so I have seen spots red slimy stuff growing on my rocks and close to frags. This has been happening in high and low flow areas. I am guessing this could be a form of cyano which I brush and siphon out. Also, my sandbed and glass panels go brown with a stringy organism...

Hello, so I have been into the reefing hobby for about a year and a half now and about 4 months ago I purchased this 30 gallon tank and cycled it, and placed a few fish and corals in. I am at about the 3-4 month mark and all of the sudden this strongly algae began to grow very quickly and in a...

I'm finding myself using a lot of peroxide now, brushing stuff off with it, and dosing it nightly with the 1mL/10g that's commonly recommended, and it's completely turned my tank around! This feels like miracle stuff! What are the long term implications of using it? I had a horrible...

Wanted to share my experience with the effectiveness of H2O2 baths This whitetail tang had an advanced case of velvet, and after a few days in the QT was on deaths door :( I ended up treating him with a 30m Hydrogen Peroxide bath (following @Humblefish instructions) followed by a standard...

ok so my duncan was closed for a few days i was like oh that’s fine then i noticed white stringy things and they retract when touched now i know they are hydroids and i know blah blah terrible spelling no commas i’m kinda in a rush atm but here’s what i did i took my turks- baster thing filled...

I recently bought 10 pounds of live rock with green hair algae (I got it for an extremely good deal at $.50 a pound). The rock was out of water for a day But was still moist when I bought it. The rock has been sitting in a bucket with water and a powerhead until I can figure out what to do with...

29 gallon mature Aqueon tank with HOB filter and HOB skimmer, 2 Hydor pumps for circulation, 1/2" sand bed and pukani rocks. 1 large BTA, and numerous SPS and way too many kenya trees. Small purple tang, mature standard clown, and blue spotted jawfish. Shortly after I removed my skimmer for...

I understand they have stabilizer agent in it, so was wondering if anyone that ever uses Hydrogen Peroxide, do you exclusively only use the food grade version?

From what I understood, 3% Hydrogen Peroxide dosed 1ml per 10 gallon, once daily. Is there anything else should I be aware of? Do I dose in Sump near overflow chamber so it get the chance to dilute before reaching return? Should I be getting 6% for stronger dose or 3% is okay? I will take...

I have a 29 gal BioCube reef tank that has been established for 2 years. About 3 months ago, after some neglect on my part with infrequent water changes, I noticed some red slime algae. I got some stuff from my LFS "slimeanator", it wasn't the yellow powder, it was a light blue liquid that I...
