.25 GPH drip emitter

[nfored]

I have googled until I could google no more. The smallest drip emitter I could find is .50 GPH which is about 12 gpd. I am really shooting for closer to 4 gpd , but can accept up to 6 gpd.

My thinking here is hook the line in up to a pop bottle and poke a small hole in the bottom. Basicly trial and error, unless someone has a better idea?

using a small needle valve to slow the flow down even more. Are you making a nitrate filter?

you could use a small ball valve and just manually adjust the flow rate.

I want to make a drip system to replace 4 gallons of water a day.

For a very slow tuned flow, a needle valve is more accurate than a ball valve for calibrating a flow. You can get them for airline tubing as well.

So i just found out I can't use straight Reverse Osmosis water in my aquarium. So my new question is, would it be safe to setup two drip emitters one straight r/o water and one tap water that has been ran through a 1 micron carbon filter.

Then have the two emitters dripping into a container that then drips into the aquarium, this way I get a 50/50ish mix of r/o and tap? will the carbon filters take out the chloramine. I know that the 6 stage r/o should remove the chloramine, but if i haev to mix it with tap then I need to address this issue.

Agreed. Thats what i use to slow drip diluted prime into my tanks and it works great ive dripped down to about a drip every 30 seconds which is alot less than .5 gph.

Why can't you use straight R/O water? R/O usually includes charcoal and micron filtration.

You don't need it to be a constant flow.

For example, you could use a larger GPH (e.g. 1 gph) emitter and have it on for 4 hours (...or .5 gph for 8 hours) to achieve the same effect (4 GPD).

I've used a simple, battery operated lawn sprinkler timer (available at any Lowes or HD) to set the stop / start times for water.
