@brokensword The main problem between a FB group and a forum like GPF is that on the FB group, there is no back and forth. No exchange of ideas. No interaction. No follow-up. Usually, WYSIWYG……. And, unless you “save” a post, there’s no way to get back to it (unless you can recall the member’s name…..) in the future. I don’t think it’s a good set-up (FB platform) for addressing problems, but it’s fine for showcasing ponds. In a nutshell, THERE IS LITTLE EDUCATIONAL VALUE, just a jumble of confusion. I feel sorry for the newbies who haven’t done their homework in the first place and have no idea about pond chemistry and bio-interaction.
Personally, I don’t post in these groups, but will occasionally answer a question. In this case, I commented that the pond “might be too small” and recommended GPF or KOIPHEN. Many others commented that the pond was going to be too shallow (it will be), but no one addressed the overall size and relationship between depth and surface area….. Based on this single post, I see a lot of questions that need to be asked of this poster.
