flow valve for slow drip

[Reybeast]

Howdy, I am looking for small flow valve, like this: http://www.marinedepot.com/Korallin_Flow_Control_Valve_(Orange)_Calcium_Reactor_Replacement_Parts-Korallin-KL3129-FICRRP-vi.html

or a pinch valve like this: http://www.marinedepot.com/Flow_Control_Pinch_Valve_Calcium_Reactor_Replacement_Parts-Plumbing_Parts-FT0002-FICRRP-vi.html

preferably one of each.

Also need a reliable heater for a 25 gallon tank.

Oh, and a drip line holder, http://www.marinedepot.com/Bubble_Magus_Tube_Holder_Dosing_Pumps-Bubble_Magus-4W9113-FIDPDO-vi.html
