Fry Growout tank plumbed to parents tank?

[Soccer]

Hey all,

Okay so I just received Joyce's book today and haven't had too much time to get a really good feel for everything but I am picking some equipment up tomorrow and thought I'd run this by people. This is my first attempt at breeding and I have more reaserch to do still. I am thinking of having the parents tank, with the breeding pair on a shelf in a 20 gallon. Then plumbed below would be a growout tank of about 30 gallons (Don't know if this would be too small). I would build a seperate area for a skimmer and auto top-off in the 20 gallon, and flow would be provided via the return pump to the maintank, and a small powerhead for the growout tank. The period where the fry is on rotifers would be done in a seperate 10g. I am just trying to see if this would work, without contaminating the maintank. Would the growout period provide too many feedings to be plumbed to the maintank?

Anyways, let me know if its a bad idea or way off, lol
Thanx for any help

umm, it's just like adding bioload, as far as i understand it, of course i'm only ahead of you in that i've been asking questions for a week or so, no tank yet for grow out or anything, just be careful of warning about power outages and using up all the oxygen, since youo'll have a lot of fish in a small tank and if the flow stops, so does the oxygen,

In Wilkerson's book, she mentioned this and said she quickly poisoned the main tank b/c the feeding WAS too much bioload for the larger tank to accomodate. I think the only way to keep up with that is with water changes--it's going to be much easier changed 5 gallons than 50!
