Jebao Dosing pump thread.

When you guys got yours.Did you pull and get the grips out of the hose in the pumps.Not sure if im supposed to or not.Instuctions said nothing about it.
 
With all this talk I'm wondering if I did something wrong. Because my doser's been running since 3/25/15 I programmed it to dose 10ml each of 2part twice daily and well my parameters are spot on.
What is everyone using to measure the actual output?
 
The easiest way to measure the output is with RO water and a pair of scales that measure to 0.1g (they are useful to have around in this hobby anyway). 1ml = 1g.
 
Can a few of you guys post some pics of how you mounted this unit. I want to get one and put it under my tank, where my sump is but it seems like it's better to mount it with it being higher and dosing down. Not much space below my tank to visualize the display and have the pump lines pointing down. Does that make any sense? Kind of hard to explain.
 
It just seems that mounting it under the tank seems hard being that the display screen is on top of the unit and it doses from the side down, like it should be mounted up higher.
What is a non-return valve?

Non-return valve is a check valve.

I should be getting my DP-4 in a couple of days and I am planning to install it flat against the side of my stand. Will drill 6 small holes on the stand to send the hoses through it and will also try to find a couple of good looking brackets to hold the pump in place on the outside towards the back of the stand. Can anyone foresee a problem with such an installation?

I agree the arrangement of the screen and dosing pumps is not optimal.

I have a raised sump so the doser is actually below the sump, flat on the floor of the stand with the tubes overhanging the base of the stand.
 
Has anyone tried to cheat the calibration? Instead of 100ml tune to 20ml so every 1ml you program is really .2ml

Set mine up today. I'll test calibration in a couple weeks again but I like it
 
Set mine up a couple of days ago. I installed it flat against the side of the stand. Asked it to dose 15 ml 12 times a day. Checked for accuracy today:

I am using this for a different application but maybe you can help me. I want to set this up to dose 6ml, then have it dose on command, manually. No automatic. just hit a button and it doses. Is this possible?
 
No manual dosage is only momentary. Why wouldn't you want automatic you might as well just hand dose the supplements

Yes, you can dose manually with this pump. Although that (to me anyways) negates the value of an automatic doser.
 
I have been thinking about getting this doser but seeing mixed reviews. I am new to the whole dosing thing. I just want my alk, cal & mag to stay constant.
I keep seeing it says it needs to be calibrated how is that done?
Next question is how much chemicals do you put in those containers? The containers that you can get when you order the bundle package from Fishstreet.
 
Mine is great.Been running a few months. It was super easy.Dont let the word calibrate scare you.I even found the direction s to be helpful.As far as containers, I use empty vinegar jugs .Just rinse them out.Lable them.I like the 1/2 gal jugs.Also there are plenty of video s on set up.
 
Can anyone PLEASE tell me exactly what size is the replacement silicone tubing for INSIDE the DP-4 pumps? My maintenance customer just bought one of these units on my suggestion, and the dang tubing is all kinked up, and messaging the kinks out is only a temporary fix, it goes back to being kinked in a single day, completely stopping the doser on all four pumps. He's ready to fire me if I don't get this fixed like NOW, and I can't for the life of me find the replacement tubing for them. Please help. Thanks!!!
