OK, so I'm REALLY surprised by all the comments regarding water quality - it was my experience in FW that the grow-out tanks did much better when water quality was better (i.e. they got 50-75% water changes every week). Grow out happened faster, you could pump more food through the fish and get them to market sooner. WHY are there so many folks saying (to some extent) "ah, don't worry about the grow out water quality, keep the BROODSTOCK pristine"...last I checked the adults were better able to handle poor water quality than juveniles, or is this just all TOTALLY backwards in saltwater fish breeding?

My take on it is that the parents will tolerate lousy water conditions, but you run into two problems that I can think of right off the bat:
1. The parents won't/don't/can't spawn in lousy water.
2. Less than ideal water quality while the eggs are developing results in much higher initial mortalities on the first and second nights.
Also, because the standard accepted practice is to transfer parent water with the eggs for hatching out, it's much easier if the parent water is as clean as possible to start with.
In a perfect world (or at least cheaper one) having pristine conditions for the growout system would indeed be ideal, but when you're jimmie-jammin them in 10 to a gallon (to spread the hate around some) staying on top of water quality is a full time job
