This is Literally My Dream

I can't stop watching this video. It's really long, but SO interesting. I love how they use the plants to pull all the nitrates out of the water so they don't have to do water changes, they just top off for evaporation.

Once again, if it weren't for YouTube, maybe I'd get some work done.

Thar's really cool...!

I did not have the time to watch this long video (this is why I am an article person, as I am a speed reader and I like to follow citation links too)

This said, using plants to pull out nitrate is NOT a novel concept (maybe for Cory), in fact we've been using this for decades, especially in ponds using Veggie Filters. In fact I was one of the early persons in the industry using Veggie Filters back in the early 80s

The one point I would make is that with little or no water changes, the closed system of an aquarium or pond will slowly go out of balance as per Redox & electrolytes if no outside ionically charged minerals are not added

According to the guy who owns the fish farm, they do add quite a bit of water into the system to make up for evaporation. Given the heat in some of those greenhouses (120°F in some) I would imagine that evaporation is huge.

I think Cory's point is that they have so many plants going that it functions like its own ecosystem. The high volume of plants, especially plants like mangrove, eat up the ammonia and nitrate produced from fish waste. I've seen lots of videos of fish farms, but most don't have any kind of veggie filter to eat up waste. I thought this one was so cool because of the organic system they have going.

My experience has shown that addition of water for evaporation does not keep up with mineralization. This includes aquariums with large sumps that have high evaporation rates.

Do not get me wrong, I think this is an awesome idea, I just find it interesting that this is so Novel to Cory.

I will also have to admit a bias, I've seen many of Cory's video, and they are packed full of misinformation and outright lies.
He has made totally inaccurate comments about companies such as ATI, made many incorrect statements about diseases, medications, treatments, and has used our information without permission to sell product.
