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.
