I’ve been dosing H2O2 (hydrogen peroxide) for months and there are many threads here about it. I started dosing when I got dinos just to help with the battle. Dinos went away and I stayed away from algal blooms. I then got some cyano in some low flow spots. I added flow but also started to slowly dose more H2O2. The end result was clean beautiful purple rocks. So I dose 5 mL (6% solution) daily by hand to my 130g. Only downside is my zoas close up for 5 minutes almost immediately but have no long term downsides.
Here are the beautiful, clean purple rocks with healthy SPS.
Curious to hear others’ experiences. And no I don’t see this as a fix to algae problems but just part of a maintenance regimen.
Good question! (I have no idea but hope someone does.)H2O2 stops working when it is subjected to light. I wonder if fuge lights would do this as well. I am sure if you dosed while the DT lights are on, it wouldn't work as well. I am wondering if my fuge light would kill it, stopping it from destroying my macros.
I’m just finishing a twice daily 10 day, 3%-H202 at a rate of 1ml per gallon, lights out treatment and I’ve had no problem whatsoever with either my Fire or my skunk shrimps.@brandon429 You mention Lysmata shrimps, I have a skunk cleaner, is H2O2 a no no when you have one of those? I wouldn't want to kill it but I'd take the help with unwanted algae...
I had great luck with mine dosed 300 ml of 15% H2o2 with approximately 150 gallons of tank water. It did kill a ton of gha.No id say corraline algae is the secret to clean corraline covered rocks
Im the h202 king here. Ive dosed more than anyone ive seen here. Ive dosed 10ml of 30% peroxide into my 125 gallon. It kills mostly everything, algae, corals and irritates fish at that amount. Finding the sweet spot is hard. It literally dissolves algae. For me its useful but comes with caution and risk.
300 ml of 15% all in one time?I had great luck with mine dosed 300 ml of 15% H2o2 with approximately 150 gallons of tank water. It did kill a ton of gha.
Yup! For 3 days straight day and night.300 ml of 15% all in one time?
Sorry 5 days straight.Yup! For 3 days straight day and night.
Ok you win lol. Any corals? When i dosed 10ml of 30% the skin of fish would bubble from it. If i dosed 125ml of 30% which would be about the same as 15% at 300ml to 150 gallons, i think it would kill my fish too. But i didn't have any sand its bare bottom so its possible having less organics to oxidize increases its effect. 10ml killed dinos very well. But they always came back. Uv sterilizer got rid of them.Yup! For 3 days straight day and night.
