Jebao Jecod DP-2 Programmable Auto Dosing Pump, 2 Channel

I lost mine somewhere in my mess, but I have same like this, but 4 pumps and it's great for the price you pay. I would like to see weekly schedule, which would make it better for dosing micro and macro alternately, but... you can't have everything when you pay that little. Go for WiFi version if you can spend a bit more.

Product would power on but wouldn't hold memory so I could program dose schedule.

I had purchased on of these units about 6 months ago & have had very good luck for dosing Alkalinity & Calcium my BioCube 14. I is very stable. I was using BRS 1.1ml pumps on my 20 gallon long & it was time to change them out for a more compact unit.The second unit I purchased is up & running well & I have had no problems with either unit. They are very quiet. The only downside is that they are a little tedious to program but once you are done it is easy to change & modify the program.NOTE: The is an error in the instructions for the "Interval Days". You will need to select "0" for everyday NOT "1" as stated in the instruction booklet. (Videos are available on YouTube & Correct Instructions can be found in the Internet)would be a 5 star except the programming & Instruction issue.

Using this pump to dose 2 part in my reef tank.Plugged it in and set date and time and some settings. Unplugged it for 24 hours to simulate power outage. Plugged it back in and date,time, and settings were correct so it passed that test.Easy to calibrate using a measuring cup with lines for milliliters.One star deduction for instruction manual. As you can see from my photo, it says interval day setting 0 means no dosing. Setting 1 means everyday. THIS IS INCORRECT!I had to look up the manual for the DP-4 (same software) online. 0 is everyday and 1 is every other day.When it didn’t dose on day 2 I thought it was defective. If you want to dose everyday, use interval day 0.

I purchased this product for it's ease of use. Previously, I had ordered a WiFi dosing pump but found the pump totally useless when the poorly designed product app refused to connect to the unit. I am very happy with my choice.
