I have seen such systems and their consequences. Once hydra breaks out in any tank, the infestation spreads to all tanks on the system. This is true of any desease or parasite -- it's just that hydra is easy to spot and to observe how it spreads. I'm designing the room so that (eventually) each tank will have a dedicated hose that connects to a common drain pipe, and each tank will have it's own valve providing fresh r/o water, but what water goes into one tank will never go into another tank. I'm also establishing a section for quarantine tanks so that no new fish will go into one of my established, aquascaped tanks until they've been in quarantine for at least a month. I do get a good amount of wild-caught fish and I've been burned before by cutting corners. We all know that quarantining fish/plants and isolating tank water is the correct way to do it. So I made that a requirement as I redesigned my room. --Randy http://characin.com ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@listbox.com.
