Yep, I am still thinking and thinking how to improve the efficiency of a closed aquaria system.

Here, I was just reading the latest issue of Aquaponics Journal where scientists has been building anaerobic tanks to help digest waste (liquid and solids) from the pigs and chicken farms. And as the anaerobic bacteria fixed NO2 and NO3 back into O2 and free nitrogen, the nutrient rich water is fed back to a algae pond.
This is somewhat what we all have been trying to achieve thus far as well with DSB and refugium.

I want to take it a step further. Remembered that the discussions of building live photoplankton reactor? One of the problem is the water being used. We have been discussing about passing the water through UV tubes to kill off any pathogens and microfauna that could wipe out the algae culture, but still fear that if anything survives, the culture would be wiped clean. Well, I think we can try passing the water through a anaerobic chamber first (or 2 of them in sequence). All living free floating organism would be dead passing through the anaerobic chamber, leaving the water nutrient rich and microfauna free. Aerating the effluent will kill off the anaerobic bacteria and the effluent can then be fed into the phyto culture chamber. This way, nothing in the water is wasted and a complete closed system "could" be achieved.

The system can be completely run by itself with just a dosing pump to regulate how fast the flow through rate be. The phyto can then be used as is or be connected to rotifer or artemia chamber.

What do you guys think?

hi.
The flow rate thru the chambers will be very slow, unless the chamber path is very long for the anaerobic section to work. To degas all the oxygen out and to kill the bacteria is not that easy. pores of bacteria/algea may survive for ages before they spout. UV is more efficient than the chamber setup.

Nice idea man, nice. Im still thinking that Ozone may actually prove usefull afterall when used in this capacity. I think it may be a better way of ensureing steriliseation than UV and quicker than de-oxygenation.

But for the Ozone to work i think you would need a sort of surge system. Basically you would have a chamber filled with tank water, bubble Ozone through it for a while, then cascade it through the various planctonic cultivation units. As opposed to a constant flow.

Defenately a tricky endevour, but worth its weight in gold IMO.

How about adapting a multi-stage reverse osmosis unit with some extra prefiltering to keep it from continuously clogging?

hi.
Running RO on salt water to get rid off the bacteria? Well, the implication is that we need to add salt to the output to make the salinity constant.

I suggest (as an alternative) cold sterialization with a pressure pump.

What i kinda meant was that the water would have to be extracted, stored then sterilised before addition to the first planktonic culture. I sould have said a systemised system. I suppose that would be a better way of describing it.

Go check out the thread called photo's from a hong kong reefer, he has some nifty brine hatchery allong with this rottifer thingy. Not quite the same i know.

The last word i heard on the steriliseation was that there may be some drinking water dispencer sterilisers that would work.

im going back to my hole to hide now.......

Actually, Craig Bingman is working on something similar to this and spoke briefly about it at a local club meeting in LA. He's got the first part handled (sterilization of incoming tank water through use of hydrogen peroxide to create a nutrient-rich import water), and is working on various sizes of chambers and flow rates for the phyto- and zoo- plankton chambers.

Could be a big boon to the hobby to povide constant zooplankton to a reef tank - I hope he's successful.

Kevin,

You got some URL relating to Dr. Bingman's new R&D? Very interested in seeing how it is "supposed" to work!

The gentleman who was trying to use peroxide. I think he has a article in the annual marine fish monthly. I think that is the name of it but the issue has a trigger fish on the front. But it uses a uv sterilizer and the hydrogen peroxide. It slowely moves water through the sterilizer and adds the peroxide and also CO2 so that calcium doesnt deposit on the quartz sleeve. It was a very intresting article i will try and find it tommorow it is hiding in my house somewhere.

Working out the container sizes is easy, and the culture growth rates are condusive to cascading system, ie the green culture grows much faster than the zoo culture, potentially allowing a mixture of both zoo & green to be added to the aquarium at the same time.

UV Sterilizers, C02 and hydrogen peroxide. This is starting to sound like a very expensive system allready.

What about a fresh water system that could be run from the evap top off. Of are fresh water Phyto's and such no good for our salty freinds.

The person you're referring to is our Science Editor, Craig Bingman. The article appears in the last Annual I edited for Fancy Publications, Inc. It is the "2002 Marine Fish and Reef Annual." The publication can be purchased from Inland Reef, one of our sponsors.
