    If you wanted to be spiffy you could use a relay between the PSU and the device and then your controller could effectively shut off power to just one device. But unless you're really good at wiring and cramming things into a large project box, that would be quite a messy jumble of wires.

    The lights are controlled by internal controller, connected to the network. (AI prime)
    Main pumps have speed buttons. (Jebao)
    The only thing on my Apex relays is/was peristaltic pumps and heaters.

    If you have 17 power bricks, you might need 3 or 4 of the better ones. Or larger/smaller ones.
    You need to make the amps come out even.

    For me it was more about having higher quality sealed supplies, not the actual count.

    Another cracked fitting. On my GFO reactor. Of course it was in the back.
    At least the drip went back in the tank.

    Pipe is not so important. But I have had a couple of female fittings crack.
    And I use lots of teflon tape, and am pretty light with the pliers.

    What is the black fitting there?

    Too much tape could cause the crack too, you wedge it in their with not much of a gap especially if there isn't a taper.

    It is a 90 degree elbow, male-thread to female-thread.
    Standard sprinkler fitting.

    Kinda seems over tightened to me. I only use 3-4 wraps of tape, but prefer liquid teflon. I also usually don't use pliers at all and only hand tighten. Those nylon fittings are harder tho. What's the sprinkler fitting made of?

    Not sure what type of plastic that is. Softer than normal PVC, but not nylon.

    Note that it lasted for a year or two before cracking.

    I usually finger tighten also, but that little nut is not so easy to turn, so I used pliers.

    I often use silicone instead/also. It both lubricates, then dries really water tight. Easy to get apart.
    But that can crumble loose if joint "works" at all.

    New fitting is a normal schedule-80 elbow.

    I meant the male threaded fitting is nylon, and yeah they are tough to tighten. I would stick to materials you know what they are instead of sprinkler pieces that probably aren't made for saltwater.
    Liquid teflon isn't the same as silicon. Works well.

    Not so worried about sprinkler parts and salt water. Mostly just that they are built as cheaply as possible.
    But I had them in the garage ... so ...
    Like I said above - schedule 80 - from now on.

    I will look at liquid teflon. :cool:
    Never used that.
    Looks like it is safe for drinking water, and resists most chemicals.

    Liquid telfon does work great and is used all the time for potable water applications. It's just really messy and it never dries, so it stays messy.
