My journey into automated dosing of ferts

So I love my planted tank but hate dosing it in the morning before I go to work.

I ended up purchasing dry ferts from GLA since I have been using seachems line for a while. I mixed them with 1500ml of distilled water and calculated out doses of 10ML (1/3 dose as recommended for low tech).

I bought a Jabeo DP-4 so it has 4 dosing heads, its pretty straight forward on how to set up and use. If you have any questions let me know, took me all of 10 mins to figure out. Just make sure you calibrate it when you first get it.

My programming is

PUMP1: 1 dose every day of 5ml @7:00 am Excel
PUMP2: 1 dose every 3rd day of 10ml @8:00 am CSM+B
PUMP3: 1 dose every 3rd day of 10ml @8:05 am KNO3
PUMP4: 1 dose every 3rd day of 10ml @8:10 am KH2PO4




This is my first day with it set up, so I'll try and answer questions and update it as I go, or find issues, etc. I know a few people have looked into it but I haven't found much info on it in the freshwater community.

I'm surprised more people don't do this since its pretty popular for dosing 2 part in the reef community.

I've seen some pretty complex auto-dosing setups on here, from arduino controlled magic to jerry rigged peristaltic pumps. After googling the price for the Jabeo DP-4, I'm also really surprised people don't go this route more often. Good luck and thanx for sharing.

Look forward to see how this works out for you. Has anyone also tried dosing food for vacation time?

will do, seems like everything is going as planned, seems to be dosing accurately and i can sleep through it haha.

total cost is under $90

$73 for the pump,
$6 for tubing
$6 for hard tubing for dosing containers (glass milk jugs)


This is prob the best thing I've spent money on in a while!

This is a really sweet idea! I also can't believe more people don't do this, especially on bigger tanks.

I'm using mine to dose 1-3ml (depending on the solution) every hour. Combined with an automated water changing system, this allows the maintenance of a consistent TDS of the water.

You can also purchase the DP-4S which is the slave unit and will be controlled by the main unit as in the OP.

Feel free to edit.

So i was checking on it today and noticed a decent amount of air in the lines, looks like i didnt spend enough time bleeding the lines, so i manually dosed them into their containers until most the air was out.

Version 2 of this was released, pretty sure i have version 1 . V2 apparently fixes the issue with air in the lines. Fish-Street seems to be the most active jebao retailer and it might be worth it if you are looking for one to pay them the extra money to make sure you get a v2.

I ran into this thread saying that the pumps internals may be installed incorrectly compared to the other higher end pumps that they copied.

I went ahead and tried it and i still get air in the line from it not pinching 100%. So I ordered Check valves to install into the intake of the pump to stop it from happening. Ill get them Friday and try to update you if it fixes the issues.

This looks amazing! I know what I'll be using my play money from my next paycheck for!

It will be really nice to have something that will dose my tank right before the lights come on while I'm at work.

Thanks for the share!

I have a very similar setup. The pumps work very well, but sometimes the tubing gets air in it. I put in check valves in the outputs but it doesn't seem to help that much. It makes it tricky to do daily smaller doses since 1 of the 3 ml may be an air pocket.


Overall, it beats doing it manually for sure!

i have put mine on the intake, its litterally the first thing that the solution goes through, my check valves are inside the bottles. Ill let you know how it goes.

Hey Slythy, any luck with your setup? Have you seen less or no air in your auto dosing lines?
