So im tired of dosing calcium manually and im looking into a dosing pump to take over the job. Looking for something relatively inexpensive or cheap to make.
Who has experience with a good dosing pump, what type of pump is it, what and how do you dose and how often? Any DIY dosers? thnx

These are rather inexpensive and work very well. http://cgi.ebay.com/Aquarium-Peristaltic-Dosing-Pump-2-control_W0QQitemZ280641624177QQcategoryZ3212QQcmdZViewItemQQ_trksidZp5197.m7QQ_trkparmsZalgo%3DLVI%2 6itu%3DUCI%26otn%3D5%26po%3DLVI%26ps%3D63%26clkid%3D7730358998444338404#ht_1080wt_1141

I use 2 of the pumps from apt instruments. Cheap box with a couple holes and you have a dual doser.

Can u show me what ur talkin about(the pumps)? Did u make the box urself, I could easily do that. I am hoping for something cheap maybe around $50.

I'm using these: http://www.aptinstruments.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=AI&Product_Code=SP100FO&Category_Code=SP100

They are $65 a piece. I have 2 of them mounted in a radio shack project box. All you need is a pump, power cord, digital timer, and a box.

I c, they have cheap Chinese pumps like these on eBay but I am not sure I understand how to hook them up, basically just a power supply and timer then intake tubing and output tubing? What kind of power supply did u use? Just a power cord or 12v dc?
If u could show me a picture I would b super greatful!
