Russ,
I don't know about up North but down here in Socal, at every single home show, we have these big R & G type ponds on display, and everyone see's them and go oh how beautiful I want one of them in our yard. Now of course at the home show they have these BIG Koi in them swimming around. These water features were of course just set up and will only run for 1 to 2 weeks. i am sure they are doing massive water changes to keep it looking so pristine. With this type of advertising people dont even think to ask "is it ok for Koi to be in this shallow R & G water feature".. They have already seen koi swimming around in it.
Six months to one year later: they are calling all the "real koi dealers" and are asking why are my fish dieing? why do they have soars? why do they keep getting eaten my preditors? And of course the customary answers, so sorry, pond is a water garden NOT a koi pond, over stocked, go bye some goldfish, take the rocks out, do water changes, dig it deeper, add a real filter.. Then you get the customary answer, my pond is a eco friendly pond, I do not need any of that, my installer told me that we only need to cleen it once a year, and that the koi dont need any food, they will live off the plants. And we do not need to do water changes.
12 months to 18 months later
Same person calling, all the exact same answers..
18 to 24 months later:
same person calling, same questions, but this time they are actually listening, and they finally say what do I need to do to make this a healthy and easy to maintain "koi pond".
That is were I have a problem, false advertising, people dont ask some questions, since they already see koi swimming in the R & G at there local home show...
