If we could get the ozonated koi clear Gel out to the US it would sell because it quite simply is the best treatment weve ever come across for Ulcers Marshall :-

Its based around a treatment that the Japanese use on humans and I hve yet to come across anyhing that will evenm come near to the results this treatment gives , including perfect scalation after the treatment not just a hodge podge of scales jumbled together as it used to be with ulcer treatments

I forgot to mention that I monitored the koi after my huge water loss disaster a few days ago and kept a check on PH etc. as you had recommended and they are all doing fine now. The big silver koi did act a little weird for a couple days but even he came around and they are all back to normal now. I did add several redundancy features to the pump and flood systems so I hope I never have to deal with the problem again.
