    Hi All,

    I am considering building myself a dosing station (3 or 4 station).

    Never ordered anything from eBay ... what's the experience like ?

    They reliable ?
    What delivery method did you use?
    Expensive ?
    Import taxes ?

    So far so good. Very simple tech, dc motor and some plastic rollers, so I dont think much can go wrong. Paid about R500 including import taxes for 4.

    Got it from Hong Kong and it shipped via the china mail, sa post office. Took about 3-4 weeks.

    Cool .... do you mind pointing out which ones you got (if you can remember) and also would you mind if I contacted you once in a while to check on my design and build ...

    As far as I can figure out (and I may be wrong), you basically have to tell the pump to pump for x amount of time - right ? ... simple timer, or am I wrong ?

    Also not sure how to control the flow rate ... so would appreciate some help there if you don't mind

    Jip, that is about it. If you're supply is fixed, 12 V for these pumps, then the flow rate should be constant (just calibrate it when you get it. the ones I got gives about 70ml / minute). If you have a timer to switch on for the needed time every day then that is fine, is what I do via an Arduino controller.

    Nice, ok that's easy enough. WIll just get a basic timer for now. In time I am going to program a PLC to do all my aquarium controls, which will include my DIY LED light (when I get to that - after the dosing station). The PLC will allow me to have much greater control over the dosing station and I will be able to set the required daily times, etc.

    Thanks for the "chat" mate - appreciate it .... gonna hit the sack now ... cheers

    Cool, PLC would do the trick nicely, enjoy!

    just saw toy thread now man... so cool wow!!!
    do you use the potentiometer for controling the amount of flow?

    Thanks @HOT SAUCE. Yep, I had to because 1.5 volts is way too much, the fluid flows too fast and too much. So this will work a lot better getting power from an arduino or similar.

    I have found a place that could possibly supply - called Verder Pumps. Just waiting for a quote from them.

    If the pricing is ridiculous, could I order mine together with you and we split the shipping costs ?

    I saw your thread and it looks pretty awesome and very inginuitive .... my problem is that I want the 24VDC models specifically because I am using a PLC to control the pumps and the rest of the equipment on my tank so it would make life much, much simpler if they are 24VDC.

    Please let us know.. last time I checked with them, it was rather rediculous. but I think its because these come with the control box. and not just the pumps.

    Is the output voltage to the pump 24v? I'm sure you can build a small circuit to limit voltage from the output. So it can go between output and pump.. if that makes any sense:p

    I saw that on their website but there is a part of the website that shows the "head" only. That's what I have asked for ..... let's see

    Sure you can .... just another point of failure though so I would prefer the 24VDC ones instead.
