I have a jeabo dp-4 - saw many videos where folks are doing well with this dosing pump. Also saw information about how to "fix" the pumps as they come assembled wrong. Been through all of that.
I have a RedSea Max Nano (AIO) tank so my dosing requirements are small - like between 1-5ml at most per day. The pump programming will allow it - but I have issues with it no matter what I try. IE - for small dosing amounts, you have to throw the directions out the window as the pump isn't very accurate at small dosing amounts - did that.
I've also read the pump should be above the "sump" but not above the level of the tank. No clue what that even means for AIO tanks.
In any event, the video reviews I've looked seem to have the pump above the sump - (in my case that isn't possible - since the sump and tank are at the same level). Seems this pump is able to pull solution from a container and pump it up over the back of the stand, up and over the back of the aquarium and into the water - without issue. (Unless of course you are trying to dose 1mm or so)... 10ml or more - seems the pump does fine (for those that need that much).
I guess I don't understand the logic on where the pump is actually located relative to where it needs to dose? Any input on that would be helpful.
I need to dose about 5ml daily - and it seems to me that during the 24 hours of dosing - the solution (via gravity) seems to seep back down the tubing - so next dose is less, next is less, and so on until nothing is dosing at all.
I've put a check valve at the very end of the line (where it enters the tank) - but that didn't seem to do much to help.
I'm thinking of adding another check valve down near the container to see if that makes any difference, but it I can't get it to work, it may be available for shipping if anyone is interested.
That said, who is dosing small amounts (1-5ml) with success and what pump(s) are you using?
