Breeding angels in a designed central water system (multiple tanks)?

A bit more questions on the breeding of angels: Has any one had experience in breeding angels in a multiple tank setup with a central circulating water supply system?

I have had some experience in breeding angels in single and multiple tank arrangements. Nothing on a big scale since this was still during my university days, but I did have relative good success without all of the knowledge I have now after reading up and doing a lot of home work.

However I have not come across a detailed system that explains multiple tank setups with a central circulating water system. I know the biggest concern is always possible diseases that might spread through the entire system, but the design I have in mind will be such that any tank can be isolated and either treated, or when hatching eggs to be seperated for the required medicine addition.

Any help or information in this reguard will be much appreciated.

Kind regards
Gavin
