Simple kalk drip for small tank

[dedfish]

I am thinking about setting some sort of drip up for my 20L. I have a shelf of sorts behind the tank I could put some sort of container on. Does anyone have any pictures or description of what you have or what has or hasn't worked for you?

I use to use an IV drip (like the ones hospitals use) attached to a one gallon milk jug. Worked great ...don't remember who I gave it to...Steve? I think. Similar to the Kent dosing jugs they sell.

I've used a 5 gallon water jug from walmart. It has a big spigot at the bottom and a small threaded vent at the top. I've threaded a couple inches of 1/2" tubing onto the vent opening, and secured it with CA glue, then glued that to an IV apparatus with a plastic drip regulator thingy on it.

5g is nice because you only have to fill it 2-3 times a week.
