Wow, I took a couple of days off, and there are lots of questions.

I'll try to answer them the best I can.
This is a very impressive hatchery!
I have a smaller system on a table top stand, but I am thinking about setting up another on shelving, so I am following your story with interest!
Show us a picture of the closed loop when you get a chance. I've always wondered about those.
Kathy,
I had been following your thread and getting ideas there.

The hole saw I needed to drill holes in the closed loop pipe just got here today, so hopefully I can get to work on it this weekend, and I'll post some pictures.
Just out of curiosity how many fish do you think you'll be able to produce over any given time period with that setup when running at full capacity?
chasekwe,
That I'm really not sure. It's not going to be as high as you might think. The reason I'm building this is not to mass produce fish, but more for research. I want to focus on fish that are not currently bred by companies like ORA and ProAquatixs, and hopefully help to expand the number of captive bred fish that are offered to us in the hobby.
I do plan to keep a few regular breeding pairs to hopefully help offset some of the expenses of this project (I've got four Akindynos Clowns in quarantine now), but most of the other breeding pairs will rotate in and out.
paOol,
and i thought i was krazy using a 60 gallon to breed clowns

.you are nuts mahng.
Not nuts, I just love what I do.
BlackOnyx,
Water changes? I stopped doing those long ago and everything just keeps on growing. I just had trace elements every now and then.
I'm sorry.
Ammonia and nitrite are a LOT more toxic than nitrate.
Bio tower, bioballs, biowheel, all versions of wet/dry filtering convert ammonia and nitrite(poisonous) to nitrate (vitually harmless, but stimulator of algae growth).
Nitrate can be diluted/removed with water changes. Nitrate is not the primary concern in a "breeder setup".
Ammonia is. We are not growing corals, we are feeding a lot of fish.
I am not going to spend hundreds to remove nitrate, when I am changing a lot of water daily, anyway. JMO.
Cheers,
Kathy
Kathy,
I'm with you. Regular partial water changes should be done, however, I am looking at ways to cut down on the size of the water changes. On my system a 10% water change in about 80 gallons and I've still got to add the growout system. Even at wholesale prices this is going to get very expensive very quick.
The way I'm setting the system up now I will control nitrate with water changes, then I'm going to start experminting with other ideas such as a large Remote Deep Sand Bed, sulphur denitrators, etc. I don't plan on doing away with regular water changes, I just want to strike a balance between water quality and expenses.
In the long run a breeder is making a very good investment by dealing with nitrates without having to change water.
JHardman,
Care to share some tips?
