Hydrogen Peroxide eliminating Algae

[SaltyFlip]

fishman,

did you dose on your DT and was it also 10% of total tank volume?

 

[fishman1069]

Yeah I dosed the entire system. Its roughly 100gals of volume and I dosed 10ml of H2O2 every morn for 4 days.

 

[SaltyFlip]

did you do waterchanges in between doses?

I wish I had funding to do an experiment regarding h202 concentrations and different specimens, though that would be very cruel to the livestock :\

 

[fishman1069]

I do 20 gal water changes once a week. The dosing I did fell in between the wc's. I didnt notice any effect on livestock. Even the frags I dipped are doin great!

1mL per 10g water is safe way to treat Bryopsis if doing global treatment. However, Hair Algae kinda tough to beat, so what I did with this type of algae is dip method. I also have no luck with Bubble Agae, so I just burst them. Of course we have to worry about "spores" which might be released with that method so I dosed my tank with same 1mL per 10g, hoping that avilable H2O2 in the water will kill free floating released "spores".
With regards to prior experiments I have, It did work with no deleterious effect on livestocks. Z's and P's continue to make babies, I got 2 extra eye of My Miami developing, Pods increased its population, I see baby snails creeping on my tank. I observed Sponge atrting to overun a 2 eye chalice. I gave full dose drip on this chalice. I got it from a "reefer" who scammed me, kinda worth to experiment with. I'll wait 3 days then I'll report the result. I have not changed my water for 3 months.. or more?

H2O2 is a new, cheap technique. I believe it is only for short term "treatment" since we don't know yet the long term effect of this method. We have to target the root cause once problem has been temporarily corrected. For me, its heavy feeding (concoction of seafoods pureed in a blender) plus 2-3 times a year only water change ( but my corals love it, they make babies fast and color up my SPS) that is causing these algaes.

One stubborn briopsis cluster

I killed off 95% of my briopsis problem by bringing my magnesium up to 1400. It was all gone in two weeks, except for one stubborn patch around the top rim of my peach wall hammer. I would rather avoid adding peroxide into the tank, but I'm wondering if I could kill the briopsis if I took out the hammer and rubbed peroxide around the outer rim with a q-tip. I took it out and tried to scrape the algae away, but it came back. Any thoughts?

That is something myself and Mojo Reef started years ago. The issue is it does not always work, maybe 50 % of the time and we do not know why. Also, one usually has better success if one uses Kent Marine Tech M, a mag chloride and mag sulfate sup. Here too we do not know why. For now, H2O2 is showing to be the best method.

 

[grandprixsj]

Thanks for the reply. I have been using Kent Marine Tech M. You think adding H2O2 will work better? What do you think about my "spot treatment" idea?

I would recommend researching coral dipping with Potassium Permanganate. Its a stronger oxideser than peroxide. Be careful how muc you use though, big downside is that it momentarily stains the coral brown.

I've been doing this for the past year or so, and it works wonders for turf algae when sprayed directly on the rock. Just spray then leave out for a minute or 2. All unwanted algae will turn ghost white within 2-3 days then....gone!

 

[reefman]

great info. raising mag is expensive and Bryopsis does slowly return if level is not sustain. also has side effects of killing snails and starfishes.
more experiment is needed to understand this better though.

 

[Boomer]

I agree with reefman

Be careful what you say here


Potassium Permanganate. Its a stronger oxideser than peroxide.

That is " topical H2O2", ie, ~ 3 %. It depends on strength. At the same or equal concentrations H2O2 wins.
