Scottish koi club

Like most Koi keeps who want to give their Koi the best environment possible I too have tried additives. I’ve tried Refresh, Humminic and Super Clean C and never noticed anything positive or negative in the pond or reaction from the Koi. What I did notice was a large negative effect on my bank account. Needless to say I don’t use anything in the pond except a 1/8 doses of blanket Answer against blanker weed, hopefully with my Anoxic filter I won’t even need this.

Dave,
Same here, an outbreak of open wallet surgery is never great!! but like you I saw no difference in my koi neither good or bad, some mudmuncher to keep the pipes clean, virkon aquatic now and again and that's it for me.
Regards,
Andy.
