"Grow Fish Anywhere Systems"

[HanoverFist]

quick blurb - "We call this a zero-discharge system," Bar-Noy tells ISRAEL21c. "We use biological filters and specially developed bacteria to treat the water the fish are growing in, without wasting anything. The system can be set up to raise salt-water fish anywhere in the world - even in the desert, thousands of miles from the ocean," he asserts."

So basically they invented saltwater fish farms?? :hmm4:

Raising fish in the desert

lol "specially designed bacteria." what, did they buy a whole bottle of bio-spira?

I think this is a neat idea if they could translate it into aquariums. Never having to conduct water changes would be nice.

water changes are simply a good method of nutrient transport.

He's either got a very efficient and effective method of nutrient transport, or more likely, he's blowing smoke up our kilts.

well I personally do not have to do water changes to transport nutrition, but to re introduce lost trace elements or to dilute the ones I may have overdosed.

Reef tank with no water changes makes no sense to me, there is no possible way one can add 70 trace elements, exactly at the rate at which they are removed from the system, sooner or later, you will need to do a water change.

could work for FO tank though

 

[jvin85]

whats FO? I'm a newbie.

 

[scuba-al]

@jvin85: FO stands for Fish Only, and is referring to the fact that the tank just has fish. This doesn't mean that it doesn't have live rock, it just hasn't been specified. FOWLR stands for "fish only with live rock" and is just that: fish only with live rock ---> NO CORALS!
Reef tanks techniqually, only need to have one coral, though to me, it's not much of a reef tank

I think the denitrification process is very possible. Considering their size and resource it's not too far of a stretch to imagine they've got a section for denitrification. I'm in NY so i'm very interested in touring the place!

Also has a really good point stating the trace elements. I imagine it's difficult but not impossible.

Disney in Orlando doesn't do water changes. Haven't since they opened the Living Reef in 1972.

There's really no secret to not doing water changes. Process out what you don't want and add back in what you do want. Just that a $4 million water treatment plant doesn't fall in the scope of most hobbyists.

These types of systems are possible with fish only tanks because nitrate and phosphate are not very toxic to fish, corals however are another thing. These systems are probably heavily reliant on large fluidized bed filters to convert ammonia to nitrate, micron filters to remove detritus and carbon to remove other toxins. Really the only main concern for fish survival in the ammonia step. Also look at the fish in the picture, they should be silver but there brown, probably algae but still not clean at all. Yes for aquaculture systems like this are possible but for reefs the equipment to balance the trace elements would be way too expensive for a hobbyist.

Yes, Jeff is correct.

Yes sir, I have a friend that is a veterinarian that takes marine mammal vet courses in Fl. during the summers. He mentioned this to many years ago. He also mentioned that the nitrates were off the charts and one of the reasons for not changing water was due to the regulations(enforced by fines) put into place to guard against any possible effects to the Everglades. Not sure if he was fed a bunch of BS.

Yes such discharge is very regulated in many states. For example the fish hatchery in Altmar, NY near were I grew up has a big plaque with their permit information at the point were their discharge from the rearing ponds hits the creek that the hatchery is on.
