5/7 Update: Happy to report the eye is looking much better. Tonight I am adding Kanaplex dose 2. They reacted well to Prazi powder, no visible impact to feeding, everyone is still eating everything I throw in the tank. Mixing Prazi was more difficult than I expected, magnetic stirer on full power for 1 hour (1/4 tsp in 1L of water) and there were still tiny particles mixing.
