I picked up the Tylan 200. It was a bigger bottle. The 200 is 4 times stronger than the 50 so instead of 10cc in a gallon of water I put in 2.5cc.

I disconnected the water lines and put 8oz bottles in each tub. Hopefully I won't lose any more rats but I'm not sure how quickly Tylan works. I see some red noses so I am worried.

They are drinking the water. I'm just not sure if all of them are drinking and how much they're getting each.
