If i could give it 10 stars i would. Had one of my prize Japanese imports koi got a ulcer. Followed Jason's instructions with the bacterial blast. Kept my medication tank at .5 salt and the bacterial blast for three treatments two day apiece. After two months you can see how great it is doing.
Been feeding my koi koifuel and in six months average size increase of 6inches . If you want big health koi this is a must. There color is deeper and brighter.
Momthly pp treatments are helping to clear organic waste from my pond and my koi love the Koii Fuell. Im switching from Hikari Staple.
This saved two of my fish and prior to finding this I lost four fish using brands from the big river site that did nothing. I will always have this and other products from Krazy Koi on hand Thank you for products that work!
Great product to use. Worked after 2nd dose. Detailed instructions are included.
