Sorry for not posting updates. I have been getting support from a very experienced breeder/expert (John of Hanover Koi) who is guiding me on how to keep the fish safe despite my source water issues and how to create the best conditions for the pond to cycle. Right now we are treating with salt and waiting to see if they respond well enough to that and, if not, medication will be the next step. On his advice, also switched from Prime to Ultimate to bind the ammonia and condition the water as it does not unbind as frequently as Prime and it seems to irritate my fish far less. Meanwhile, the pond it seems is in the very early phase of beginning to cycle. Nitrites have shown up and I'm hoping desperately that nitrates will follow before it gets too cold. The fish are calmer (less flashing) but still not back to normal (still pinkish), though in the mean time the cooler temps are also surely slowing them down. I feel like I'm in good hands and am planning on posting on how it all went once the fish get through this (I'm hoping they'll get through this). It's been so time consuming, overwhelming and sad that I just can't bring myself to post interim updates. But I will follow up and report back once there is more to tell. Thanks again for all the help so far.
