    Hi again.
    Below is my "quick and ugly" setup of peristaltic pump for dosing micro/macro (setup is only for testing but as you know temporary solutions sometimes stays forever :) ). Peristaltic pump is from ebay ~£19 incl. postage, rest of that stuff was more less free (12V PWS found at work, some tubes), also I had to reconnect one light tube to another timer socket. I measured flow rate and its ~ 5ml/minute so its quite convenient for calculations. Outlet I stick together with filter outlet tube over the water surface. Because the gearbox (ratio 1:150) between engine and pump itself its quite noisy I have to think about some enclosure in the future.

    That's quite a nice little setup :) Have you seen the below post on a similar DIY setup? Theres a lot of info from various society members who have played with a few DIY options, and their experiences :) It might be helpful :thumbup:

    Hi

    Cheers mate. Thanks for the link and comment. My tank at the moment is only 70L so is overkill for me ;). But I hope that setup will do the job during my holidays.

    also self adhesive skid protectors removed from old netgear switch fit nicely on the back (12v power supply as well)

    Looking good. :clap:

    The one comment I would make is that you should probably raise your plugs away from the floor of your cabinet, that way if something does leak you wont short out all the electronics. :thumbup:

    yeah, I know about that
    I'm waiting for couple of bits and pieces for my new tank, fingers crossed next month and I'll sort out that problem.
    Thanks for post

    Which seller did you buy the peristaltic pump from? I can't seemed to find anyone that sells it for that price you've quoted.

    Sorry for the terrible delay answering. I think that was unfortunately only one chance. If you'll keep an eye on ebay sometimes guys have used pumps disassembled from old medical equipment.
    Cheers
