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.
