How To Remove Meth Blue From The Water?

[xostrawberryox]

I was treating my betta in his 1.6gal with methylene blue for internal parasites, he sadly passed away during this week and now i have the empty tank. I put the carbon back in my filter and left it for a couple of days, i then did a 50% water change and rinsed out the fake plant etc. The water is still blue... grrr. My housemate advised rinsing the tank out and starting again from scratch but since he has no fish i didnt listen So, i put 2 guppies into the tank to check the water is ok (no more parasites) before i put another betta in there. The water tests and guppies are doing fine its just the stupid blue dye now!!! What to do?

Water changes will get rid of it. I use it hatching angels, it takes around five 50% water changes before it is unnoticable.

This might be a stupid question but did you use new carbon and not what you had in before you medicated? The carbon will help but it takes several weeks and would probably need changed after it cleared up. Water changes will do the trick just space them out so as not to "start over".

i take it that all that remains is the dye in the water, no active ingredients?? stupid blue stuff lol

Any blue that remains is really diluted, and won't harm anything. Meth blue stains anything it touches, this includes silicone seams & air lines. Any little bit that may leach out over time is harmless.

Just do a 100% water change. It's only 1.6g, not like you'd have to lug 10 buckets around to do it.

And risk sending his fish into pH/temperature shock? I don't think so...

Just do daily water changes until it clears up. The dye is pretty much harmless.

Which is why it would be a good plan to do it in the interval between moving guppies and putting in new betta.

Unless you are dealing with a poorly maintained tank, a 100% water change won't hurt anything. I do this on a regular basis when moving tanks & racks. I match the temperature to the tank within a couple of degrees, fill the tank, add the cycled filter & a lot of smaller angels. Losses are no different than if they were left in the previous tank, 1 or 2 out of a few hundred each week for pea body size. Once thet get to dime or better body size there are no losses.

Just do your regular water changes, and it will be gone in a month, it's really nothing to worry about.

I would have completely done a 100% nuking of everything.. if the fish in the tank had internal parasites and died, I would remove everything and clean it with hot/cold water to kill off everything.. Seems a little risky not to.. but I could just be too careful.
