I got a jebao dosing pump a month ago, seem do be doing well. I got the dosing pump under the stand and it doses straight to the DT. I’m dosing Ab+ and planning to dose phytoplankton. But it seem to not holding the siphon. The liquid seems to drop back down in the lining. So whenever it doses it not actually dosing cuz it just pushes the air back out. Any help or advice will be greatly appreciated. Thank you.
