I have a problem set up my Calcium Reactor to drip into the sump.
I set it for 45 BPM and after 12 hours I found it on 20 bpm.
I tried few times and its drip of bpm is changing.
maybe its the temperature change (its outside the house in the garage)
Does anyone else had the same prob and if anyone know where can I get plastic needle valve 1/8 for that ?
Thanks
