There are lies **** lies, and statistics
I cut and pasted this response from another thread so it could be discussed on its own merit right here. I do not want any of you to cloud the water by mentioning a single manufacturer or direct a comment at a specific person. I ask that the moderators just delete any thread where a person talks of another person or a specific product So that JUST the issue can be discussed.
The subject below has been the case for the 20 years I have been in the hobby...THIS HAS ALWAYS BEEN THE CASE. And it does not need to be, and it should be the leadership of the hobby that could step in and protect EVERY pond builder and owner from the Manufacturer/promoter's fake data.
Below is Marlo's post. He cuts and pastes BWG's post in the same thread and replies to it. The point I would like to get some consensus on is that the leaders in the hobby should be addressing issues that affect us all. And nothing affects us more than the misleading disinformation on pond pumps. We have people in the hobby that are wizards when it comes to pumps' flows and energy consumption. If they were provided with a little support then they could have the means to easily test each and every pump we felt should be considered for use in pond maintenance.
Manufacturers/Promoters of various pumps could either send their pumps or take their pumps to be "independently" tested for use by our hobby. It would be the gold standard for determining what these expensive(to purchase and operate) pumps actually do.

I think this is a major flaw in all these arguments - we all like to talk numbers, but most of the numbers we use are guesses - or worse, opinions. It makes it difficult to give much credence to most of what gets posted here. I've always wanted to install flow meters, but they aren't normally stocked by most of our Koi pond suppliers and I have been too ignorant to figure it out myself. I'm only aware of one of our members who has installed equipment that monitors watts, RPM, and flow, and because he has more money than god, one might get the impression that we mere mortals can never aspire to such a system. We don't have a good way to measure head so it's difficult, even if we know those three operational parameters for one setup, to extrapolate the data to accurately predict performance in a different setup.
It's confounding, and all the opinion wars don't help very much.
I was at Advantage Manufacturing yesterday talking with Mike and Lyann and they were very open to exploring any new pump technology and manufacturing ideas. In fact, they are on their way to China today to meet with their manufacturing and supply partners, so I hope that a little of what I told them about the pumps we've been discussing on this thread will make it into those meetings. Some negative things have been posted about them here, but I believe they are genuinely good folks and that it would be mutually beneficial for us to work closer with them to get the kind of equipment we need and to make sure the technical specifications they provide are accurate and relevant for us.
