H2O2 - overdose advice

[Nathan80]

I'm battling Dino at the min, got in tonight tired and mis-read my notes, I was meant to dose 1ml H2O2 but have actually dosed 10ml - tank is a reefer 250. Is there anything I can do? (tank is invert and coral only - no fish)

 

[Hemmdog]

How long ago did you do this? Any negative signs yet?

10ml total or per gallon? If its total you will be fine I have dosed 10ml for weeks on end in my 12g cube with no ill effects

 

[Nathan80]

Thanks for the quick reply - probably about 20-30 mins. A couple of the torches have gone really thin and sulked a bit, all zoas are closed, Acans half have contracted, half sem fine, pulsing Xenia is sulking (although to be fair that's been sulking since I started buble scrubbing and dosing vodka), green star polyp seems fine as do the SPS and the cabbage corals. Crabs are eating fine and shrimps are begging for food (those danged things never stop eating lol!)

10ml total - tank is probably about 40gallon of water, the rest decor and coral etc. The bubble tipped nem seems alright too

I don’t think is that bad .. but remember a big water change will fix any parameters problems or any extra you add to the tank good luck

I'm trying to avoid a WC due to the dino (and Cyano) outbreaks - I've found fresh water just spurs the dino on even more. The Zoa's have started re-opening now already

What concentration of the H2O2? If there will be problem - you have (IMO) already had them - I doubt it will be worser.

3% H2O2 so its not really strong

I think your in the clear.

Thanks man!

If it is going to cause an issue (and I doubt it will) the damage will already have been done. A water change will only add additional stresses at this point imo. Any reactions with the H2O2 will be complete by now.

I dose 30mL twice a day in my Red Sea reefer 170. You’ll be fine! Zoas and lps always close up temporarily. Just don’t ever use h202 directly on sps.

Not a problem at all
