    How do I do water changes on pod culture tank without sucking out all the pods?

    Hello fellow saltines, This might be a stupid question (or at least a newbie question) but how do people do water changes on their pod culture tanks? I know a lot of people keep pods in their sumps/fuges so maybe this problem isn't applicable but for people maintaining separate culture tanks...

    Multiplex APEX DOS

    Has anyone used 1 DOS to do auto water change on 2 different tanks? My thought is to use solenoid valves to control the water flow. Or to run parallel water Lines to each tank off the main lines from the DOS. If you have done this please let me know how you done it. Any thoughts?
