A very sad day

[Aqua*Reef*Man]

I lost all my fish today because of some articles and post that I have read in order to get rid of algae. I read a ton of posts that spot treating algae with hydrogen peroxide helps get rid of it. I did this and went out with my family and came back to all my fish dead. I know fish are not like a dog or a cat but I had these fish for a long time. My little guy loved them and so did my wife and just to lose them because some algae that I wanted to get rid of really sucks. To top everything that happened, I still have algae. I would not recommend that hydrogen peroxide treatment at all!!!!

Sorry to hear. I hope your corals were okay.

Hydrogen peroxide. Do you have a skimmer? How big is the aquarium?

Coral, snails, urchins, crabs all made it. Yes i do run a skimmer and I have a 75 gallon tank

I use phosphate remover and carbon And a slightly bigger skimmer than my 180 needs. But I have been testing for nitrates and I'm going to give bio pellets /carbon dosing a Try. But I change 20 gallons a week. I had a algae issue but that was before I increased flow and upgraded my skimmer. But I have like 7 tangs and way to many snails and hermits to count. O the uv helps to forgot about that.

It's wired. Fish should be much more hardy than invertebrates...

Are you keeping high value corals in your tank?

Since the fish were all dead, don't you think the hydrogen peroxide also killed most of bacteria living in the live rocks? looks like your whole system is now in jeopardy...

Damn. That sucks man. Sorry to hear.

I'm sure you've heard this 1,000 times but algae is a water quality issue. Give us some more info on your set-up.

I have a 75 gallon tank with a Coralife super skimmer 125 gallon. I am running with a aquamaxx with seachem phosguard. My lighting is a aquatic life six bulb.

I have a elegance coral, several monti's, two rose bubble tip anemones, frogspawn, mushrooms, and some zoo's.

H2O2 is pretty natural and occurs in the bodies for protection against pathogens. Strange only the fish died. Must have been overwhelming and took out your nitrifying bacteria and caused an abundance on ammonia

ouch sorry to hear this news. As you unfortunately found out the hard way tanks are all about trial and error.

My common sense would tell me without thinking twice about it or even considering dosing my aquarium with that . I'm sorry, I guess we learn something new everyday. I really hope no one else decides to try this if so i really feel sorry for you. Sorry for your loss and if i were in your shoes i would do a compete emergency maintenance. Take every living creature out along with the water and filter. I think i would even go so far into actually pouring more water in and taking it back out initially rinsing the dsb out as much as i could and starting all over again. Again, very sorry for your loss and i hope you take my advice into consideration.

PS

A couple few Turbo Snails work miracles in these type of situations.

In just a couple of hours though? I tend to think it would take at least overnight, maybe longer, for the amonia to build up to a level high enough to kill the entire fish population. JMO...

How did you do this? Did you take each individual rock out and soak in hydrogen peroxide aNd then rinse with saltwater before putting it into the tank? Or did you dump hydrogen peroxide directly into the tank? I've done this using hydrogen peroxide with no issues when I took the rock out of the tank

 

[DragonFish]

Agreed ^ I've used hydrogen peroxide before and had fantastic results, when used properly. I have dumped H2O2 directly into a freshwater tank before, but there are very specific amounts that have to be calculated first. I would not even think about doing that with a reef tank. Pull the effected rock out, brush peroxide onto the algae and let it sit a minute or two, then rinse the rock with fresh saltwater and return to tank.

 

[Aqua*Reef*Man]

What I did was I got a ten ml syringe and spot treated my algae problem in my main tank. Everything in my tank is still doing well and I woke up today and saw my malanarus wrasse swimming around. I think bc it stayed in my sand bed.

 

[bocochoco]

I guess since its an acid an has a PH of 5.8 maybe it caused too fat of a drop.

+1 did the same exact process with awesome results. One rock every other day and the system handled everything well. I would do it again if I needed to but now I run a low nutrient tank and feed my coral more.
