Tunji,

My own personal preference for handling potential supersaturation is 

treatment of all the water entering (re-entering) the culture tank as this 

allows protection from all potential supersaturation sources:  initial 

pumping, recirculation pumping, temperature changes.

If you intend to oxygenate the system with an air system, an open topped 

packed column for treating all water entering the culture tank would be a 

good bet (I'd also make at least 25% extra, in number, as spares & design 

the set up for easy replacement while operating under full load of fish--the 

media will have to be cleaned periodically).  If you're using a trickling 

filter design for your biofilter & it is configured between the pump & the 

tank, it may well do the trick.

If you're going to use pure oxygen, there are a number of contactor designs 

(including some w/no media) that will strip nitrogen from the water as part 

of the process.

Good luck,

sam

Nosy question time: If you're not going to incorporate plants yet, what

_are_ you

going to do about all the nitrate? 

 Getting a system up and running with contactor nitrogen extractors, etc.

and then

switching to a plant based system seems an awful lot of double effort.

 If you don't want to worry about keeping useful plants healthy in the

beginning,

you could always use some kind of trash plant to simply strip out the nitrogen.

 I've tried several marsh grasses and if cleaning the water is all you need,

they'll

do the trick well and are almost impossible to kill by accident so you

wouldn't have

to worry about a green thumb to keep your filter working.

Jim

I will have some water exchange typically 5% per day. However I do I go

about introducing plants into my system. I have concrete floors at my

proposed facility

Racoons are a very worthy adversary.  I had one jump up and hold onto the

storm window frame, tear the screen out and come inside to dine on a

watermelon rind in the sink drainer. - I did not get it out to the compost

pile soon enough for them:>).  The most effective control is a three strand

electric fence (4", 10" & 18" or there abouts).  On the house windows, I

now have 1/2x 1 " cage wire.  Great for keeping the barn cat's claws off

the screen as well.  If you are so inclined and live in an area where you

can, I use a Wickenkamp Live Trap with melon rind.  Then you can either

transport them to some other poor sucker's area or dirt nap them with a

well placed 22.  The liability associated with dogs is getting too

expensive in my area.  $4000 settlement for a person who drove off the

county road, down a farm lane and up to a farmstead ignoring No Trespass

and Beware of Dog signs,  got out and went up to a dog chained on the porch

and got bit.  Mike Miller

Hi everyone,

I was wondering what creative methods you are using to dispose of your dead

fish (those that are not usable for consumption).

Fish and eggshells do wonders for the garden.  Just bury them about six

to eight inches down so the flies and yellowjackets don't swarm.

Dear Deborah,

    LSU has done some work on composting fish wastes recently.  They

took a wire cylinder (1/2 in. hardware cloth?) about 3 feet across and

filled it with fish processing waste and rice hulls (cheap and locally

available).  They then put a larger cylinder with a radius about 6 in.

larger and filled that with just rice hulls.  There was no odor and

everything except some of the largest bones just disappeared.

    A friend of mine worked on it before he retired so I could ask him

if anyone needs more details or a contact person.  I do not know if

anyone is still working in this area.

We use a mix of straw, wood chips, and mature compost.  A good reference on

fish waste composting is "The Compost Solution to Dockside Fish Wastes" put

out by the University of Wisconsin Sea Grant Advisory Services

(608-263-3259).  We have never had any problems with odor, flies, or

raccoons and skunks, etc. as long as we covered the active pile with a 6" to

8" layer of mature compost.  To control leachate, we start with a 12" layer

of straw and wood chips on the bottom of the pile.  We built our  compost

bin out of old shipping pallets that we wired together.
