Very easy to pass judgement while self admittedly only partially watching two videos.
Well, yes, actually it is. I've seen the two vids, both essentially blathering the same things, and I don't agree with what I heard. Exactly how many times must I waste my time listening to him before I am allowed that opinion?
I don't like coconut; tasted it many times in many recipes and simply don't care for the flavour. Do I need to keep eating it before I am allowed to form that opinion...or can I just decide "Nope...don't like this stuff, not eating any more of it?"
I like naturalistic tanks, I don't medicate the crap out of my fishtanks every time a fish seems a little "off", and I agree that I want my fish to live in conditions that are as close as possible to those in which they evolved. I like low-tech; I adore low maintenance. That doesn't mean filling a tank with water and mud and deciding not to touch it for a few years. It means that I want the water chemistry to be as close as possible to that in nature. But a tiny volume of water in a box in my house can't be expected to replicate the conditions and complex interrelated processes found in nature, not without a lot of help on my part. I don't "need" filters or aeration or artificial lighting, but I use all of them...because they help me to
artificially create water conditions similar to natural ones. But the single easiest thing I do to achieve that goal is changing water.
Nitrates inevitably accumulate in aquariums; do you rely upon natural anaerobic activity to perform that last vital step in the nitrogen cycle, the denitrification of nitrate into nitrogen gas? Or do you rely upon plants? Or do you just ignore it and hope it goes away? Water changes would fix that for you...
There are also countless other waste products and materials that are being produced and excreted by the fish, and these are not easily and readily tested for by home aquarists. Do you just ignore them and hope they go away? Water changes would fix that for you...
My well water is pretty hard and somewhat alkaline...a common combination. If I topped up evaporation with it I would have stalactites encrusted on the bottom of my lid. Does FF condone the use of distilled or RO water...not very natural...or does he just ignore this issue and hope it goes away? Water changes would...you know...
I don't give a rat's behind how old a tank is; I want to know how old the fish in that tank are, how they look, how they grow and breed and behave.
FF takes ideas that have some value and carries them to silly extremes; that approach usually fails. He rails on about how "easy" his method is...so naturally he sucks in the lazy people who want to do nothing. He emphasizes how his method saves money...and thus grabs the cheapskates who want something for nothing. And of course he sells his FF supplements and snake oils and magic elixirs...'nuff said about that.
I am not a techie guy, but I assume he makes money based upon how many people click on his videos. What I have seen makes me think he is a shyster, emphasizing the points that appear to bolster his sales-pitch and conveniently ignoring the many that don't; he's mastered the art of the Slow Talking Con and plays up his grandfatherly persona and his back-to-nature approach to the fullest advantage. I just don't want to contribute to his profits, especially when I believe that his approach will cause far more harm than good in the majority of instances.
