    preorder questions.

    I want to purchase the apex controller and had some questions. I want to use the apex for hydroponics application.

    1.) The Apex Optical Sensors can they be used in acid/based water solutions to control the liquid level in hydroponics.
    2.) The DOS pumps will they also work in an acid/base water solution for pumping in a hydroponics setup?
    3.) What devices work with 1link? DOS, FMM, DC pump etc?

    I looking to purchase the Apex 2016 220V version ,ATO module,DC pump,FFM for optical sensor, DOS module.

    Thanks,
    Mark

    The DOS will work fine with fertilizer.

    The optical sensors may or may not be reliable. Some fertilizers leave a pretty nasty grime that may leave a film on the optical sensor and "fool" it into thinking is covered when it isn't. I would suggest getting some good float switches and a breakout box and use both

    Since you cannot, to the best of my knowledge, purchase the APEX float switch separately, what other ones would be recommended.

    Madison are the best. They dont come with a nut or mount though, so you need to order one to mount it.

    I have also used these and 4 of the 5 I ordered worked perfect for the 3 month I've owned them (one wasn't sealed properly)
