Kordon Methylene Blue Disease Preventative – Safe for Freshwater & Saltwater Aquariums, Prevents Fungal Infections & Treats Parasites, Reduces Fish Stress, 4-Ounces

Works well great stuff

This product works really well. As someone who breeds fish and also keeps Axolotls I have used this multiple times and has always done its job. Used it for preventing fungus on eggs as well as treating fungus on Axolotls gills

Great product

I have used this a couple of times and it seems to be helping with my fish tank!

I have used this to support a poorly corydora and it worked really fast

Medicating my fish

Great job

This has now become impossible to get in the UK since our main manufacturer has stopped making it. It’s sold out everywhere - why? I don’t know. Literally 30+ online retailers were out of stock & much more refused or refunded an order I made if it did show as in stock. So thank you to this American seller! Now I have my methylene blue treatment that always saves the day, as back up and piece of mind. I like to keep my Aquarium Medicine Kit well stocked of essentials. This particular brand is unknown to me other than the US YouTubers that talk about it. The smell is non existent, colour is that rich, well known MB colour we all know. Consistency is rich alike the quality brands we used to have here. Definitely value for money as you don’t need much when dosing so will certainly last me & my 4 tanks a while! Expiry date is far away so won’t expire b4 u can utilise. Easy to use, I recommend a syringe due to messiness and risk of staining. Maybe keep in zip lock bag too. Ensure bottle is wiped after use of any drips to prevent staining & of course, put away with all ur meds/chemicals. Safety cap to ensure no leakage. The wait of course is a little longer than average parcel but did arrive as advised. Recommended.

Muy bueno, con menos de una gota de cubren 50 litros

I have used this product to breed discus fish and it was very useful. I would recommend this item for sure

Devo complimentarmi con il sito. Prodotto che ha soddisfatto le mie aspettative.

I've been using methylene blue for a long time. I use it for fungus on my fish if I notice a little bit starting or if their coat starts getting a little slimy. I usually try this before I try anything else. Or if for some reason my nitrates or nitrite spike I'll use this a little bit for some added oxygen if my fish start getting stressed out or are already stressed out. This has always worked very well for me. I've never had any fish stressed out about it. No headshaking ever like what happens when I add metronidazole or praziquantal or other meds. Methylene blue has also never hurt my pond plants. I don't pour it directly in my pond. It's always been in the hospital tank. I did recently use it when I bought some water hyacinth from a pond shop. I always bring them home and put them in a container with grow lights and heat to make sure that they don't have a bunch of snails and dragonfly nymphs and whatever else there is on those things. Well, I ended up having a bunch of baby fry fish hatch from these plants. About a week later the little fry baby's started turning white and dying. I wasn't really sure what to due because I didn't want to kill these plants that I just spent a couple hundred dollars for and I didn't want to let the baby fish die. I added some methylene blue and some nitrofuranzone together with the baby fry and with the plants which also had snails, snail eggs, dragonfly nymphs on them and the white that I guess was fungus on these little baby fish I can't really tell because they were so small. I did it once left it in there for two days and then the partial water change and I didn't have any more baby fry fish die and my Hyacinth plants are still growing and still blooming. Some even flowered out purple flowers right away. So it didn't hurt them at all. I was kind of disappointed about these plants and there had to have been something on them for these baby fish to get this but not only that the guy told me that they had goldfish in with the plants. I called And asked him after all these baby fries start hatching. I think something that people should think about, and I don't know if people actually just buy plants and throw them in their ponds. I always did and I always ended up coming down with some kind of ailment around that time and I just thought it was a change in temperature, water parameters. But if the place where you buy the plants has goldfish or other fish in with them they have a fungus or bacterial infection and you bring those plants home and throw them in your pond you're going to bring that stuff into your pond. So for now on I quarantine my plants. Back to the methylene blue. It's definitely blue. I've never had it stain anything. I took pictures of what it looked like. It took pictures of my fingers after completely just dipping them in the stuff. And then the last picture I took was me washing my hands one time. It was almost completely off. Once I take a shower it's completely gone. I've never had the methylene blue stain anything that I've ever had permanently. I think that having the methylene blue around in case you have something going on and you don't know what it is is a fish lifesaver. You can at least be able to use it just in case you need to. It is better than not having anything at all. If I wouldn't have had the methylene blue on hand along with the nitrfurazone at the time I'm pretty sure all the little fish would have been dead. Because that morning when I checked on them they had nothing white on them. Later that afternoon is when I started noticing it. About four of them died. So that's my methylene blue story. I'm not sure how it would stain if you got it like on your rings or your jewelry or anything but it does eventually go away when I get it on my hands and stuff.
