Peristaltic kamoer FX-STP2 can't hold pressure from carX

[Tenten22]

Hi,

I wonder why my kamoer lone doser FX-stp2 can't hold water pressure from Reef Octopus calcium reactor?
I had tried to install a stop valve, pump runs at the lowest speed.

Please help

I’m not familiar with that reactor but do you have the adjustment tight enough on the kamoer pump?

Yes its really tight

Most likely the CaRx lid or the pH holder (with either cap or pH probe) is not tight enough. If the other pieces come apart, make sure those have tight enough fit. I've fix similar problems with different brands of CaRx and other reactors. In all cases, the lid wasn't tight enough.
