Massive Nopox Overdose

[Huskymaniac]

On Friday I was hooking up my nopox to my perilistic dosing pump and when I primed the tube I was watching the wrong line and I nce I had realized my basement smelled like vinegar I had dumped about 300ml in my 200 gallon sps tank. Since I run a 150 watt uv sterilizer inline I never got the crazy cloudy water issue atleast yet. I have also done 2 50 gallon water changes on Friday night and this morning. Gonna run out and grab a polypad today and fresh carbon changed. The only changes I have noticed since Friday have been the tank ph dropped from 8.2/8.0 to 8.0/7.8 day night respectively. My Scribbled Rabbit and Margarita and breathing a little heavier and faster but are still eating and acting okay. I have some blue shoots on the bottom on my tank that are shriveled up. Other than that everything seems good. Is the worst of it over at this point or I can expect additional issues from the nopox? Does nopox act immediately to increase bacteria? I plan on doing 2 more water changes over the next 4 days.

Might look at this thread... NoPo4x is a carbon source, just as Vinegar is:

EMERGENCY - Accidentally pour vinegar into a tank

So, my ATO was not working so I had a vinegar jug of rodi sitting around next to my newly cycled tank and I was topping it off manually. Today I was killing aptasia with vinegar in my other tank and I accidentally poured about a cup of vinegar into the new tank thinking it was rodi. My tank...

Water changes are probably your best bet.

Normally something like that would cause issues over night. I think your UV saved your fish.

I would continue to watch the fish's breathing, continue the water changes, and watch nitrate and phosphate to make sure they didn't bottom out

I’d keep a look on pH as NOPOX also contains vinegar (I believe). You could see a big bacterial bloom which a UV could correct.

Yes, been monitoring the PH on my apex. It bottomed out the first day but has remained stable, although lower than it normally runs.

Yes, I think so also.

I wouldn’t worry too much. Just watch for pH and bacterial blooms. I’ve overdosed before. Worst case scenario is cyano shows up.

I think you will probably be ok with that volume of aquarium water, but as already said watch out for any bacterial blooms and possible oxygen issues and just to be safe I would continue with a few more water changes just as an extra safety precaution

I have been up to much higher doses of Nopox than the instructions recommend, not as much as youve just added but...

The ability for the tank to bloom is also based on your nitrogen and phosphate reserves. A NoPox overdose is less safe in those with high N/P and much safer towards ulns. The UV is going to help protect against nutrients bottoming out too. The original pH drop will be corrected as when the calcium acetate (acetic acid plus calcium carbonate) is used it will free up the bonded calcium.

So for now just monitor but it sounds like your fine.

Oh and if there's available N/P the bacteria will utilize the NoPox immediately, and at tank temperatures some of them can divide every 30 minutes. So if you have enough you could have soup by the morning.

I don't think nopox has acetic acid. It states it is methanol. I am not a chemist so I am not sure if methanol would somehow become acedic acid through some chemical or biological process but I just wanted to throw that in.

Change water and test over next couple of days

Yes the only reason they state it has methanol is because it's dangerous. NoPox is acetic acid and denatured ethanol.

The denaturation is the methanol. This allows Redsea to not pay drinking alcohol taxes and sell their product to minors.

Because if you drink something with methanol it is converted to formaldehyde and you embalm yourself.

This denaturation technique began because of prohibition because many companies still needed to use ethanol. So government mandated denaturation. Unfortunately a lot of alcoholics did not understand the consequences....
