| I have been measuring the water regularly and doing water changes. I am also feeding very little. After the treatments with prazi and the water changes, I am seeing much less flashing. Probably a rise in nitrites was the problem. I have also begun to salt to .01 so far. After removing several koi, and examining closely..I have 3 with ulcers, and one with mouth rot. These problems existed outside...they are not new. I put in an order for tricide neo dip. When I see an ulcer... I assume aero & pseudomonas. I have separated these fish from the pack...they are being fed antibiotic food. I am ready to go with the dip as soon as it arrives. I would like to inject..but have never done this on a koi before. I am not going to learn now on these fish (an omosoko utsuri, sakai (H) showa)..I hope the dip is effective. I am still happier to treat them indoors now, than have a nightmare in the spring again!! My pond is frozen..but I did bomb it with PP and will do it again in the spring several times. I will then do a 100% water change before any koi enter the pond. |
