Methylene Blue

[dcarmor927]

after my tiger barbs laid their eggs i removed them and added 1/2 teaspoon of methylene blue to the 10 gallon tank...the recommended does was 1 teaspoon...my water is blue now...like really blue lol...is this bad? i mean i dont want to mess up the sponge filter that i have in there...it looks like ive got moonlighting in my tank now...i've never used this stuff before...oh and on a side note when i opened the bottle i got some in my eye...not fun to deal with...

any one who has used this please tell me if my water should be this blue? i could do a water change if i need to, but i would dump the water in the yard so i dont stain my bath tub lol...thanks

It's suppose to turn the water blue. It won't hurt anything. If you want you can remove it. Personally I stay away of meds that color the water. I hate them.

Methylene Blue is also used as a"stain" in biological samples that are going under the microscope. It helps to allow diferentiation to cell walls and makes microscopy a lot easier.

- Is your eye blue? ( i wouldnt be suprised if it was)

I've heard, (and seen) that it will stain everything and anything in your tank with a lovely blue tinge... just a word of warning.
I also seem to remember reading that it will kill off your filter bacteria, but don't take my word on that one.

I've used meth blue in the past and i got the fright of my life the first time i used it it does turn the water a really dark shade of blue but it should start to fade over the next day

The first time i used it i had live and fake plants and nothing had any stains on it but just watch if you get it on your hands/clothes and especially in your eye i would recommend rinsing it well with warm water . If you get any sort of irritation to go straight to your doctors

Also never had any problem with the filter once i've used it , tank never went into a cycle and the meth blue done the job is was made for ! lol

yea it does kill off all bacteria, if you add this to your tank you will need to re-cycle it, also it stains silicone blue too, so suckers, nets, tubes even the silicone on the tank all a lovely shade of blue. ive hatch cory eggs, using this, in a tub with just an air line, then move the yongsters to a cycled tank afterwards. If using to treat fish, do a fish bath, ie add your fish to a bucket with the dosage for a few mins, di

Thanks for the replies...yea my eye was all blue, it was trippy lol...after i rinsed it out for about 15 minutes it was fine...just burned for a bit...i can see the suction cup on my thermometer is blue already lol...fingers crossed that my sponge filter keeps its bacteria...if it gets messed up i can throw it in my 55 for a few days to build it back up a bit...i dont think the fry will produce so much waste that a daily water change wont take care of it...i also have an air stone in there with the filter so they should be fine...thanks again for the replies!!
