Hello all I bought a coral box WiFi dosing pump to use on my tank. I set it up to dose NOPOX last week and kept a close eye on it. I realized that there where a ton of air bubbles in the line and fluid was slowly leaking out of both ends. I reached out to the manufacturer and they said to make sure you install a check valve. I went ahead and did that and it helped but fluid is still leaking out of the end that goes to the sump leaving about 2-3” of dry air at the end of the tube. I assume this is a problem because I’m not dosing as much as I should? And I’ve read this could be a problem with this particular pump. Does anyone have pumps that do this? Is this a common thing to have happen with dosing pumps ?
