Simply Koi and More Koi

Anyone know if the above product is worth investing in. I'm satisfied I keep a clean system and following articles from Syd and Duncan I'm now heated. I'm always however willing to consider anything that can further reduce risk all be the kh would be a risk factor in itself. That is an area I continue to have address I'm lucky to get 1 from the tap. Thanks

to be honest i did not think it was still about?

East Riding koi company are showing it available 52.08 for 1 litre. The sales pitch is good. I was surprised that I had not seen it mentioned. .....that possibly answers my question.
Thanks duncan
