This is my dosing pump setup.  It uses a medical "feeding" pump and is fully adjustable.  This pump is a Flexiflow-III made by Ross.  I picked this up on ebay, look for seller: tanksalot as he's been selling alot of these.  I have it setup to dose 5 ml/hour.  This will give me a 32 day supply from the one gallon container.  In the container I dilute the following items and their amounts:

SeaChem Calcium        24.30 ml
SeaChem Iodide             6.76 ml
SeaChem Complete      45.10 ml
SeaChem Strontium      10.00 ml
Fresh RO water        3785.00 ml
