Deltec CRTT Help!

[Kruss7]

Hi everyone,

I’m having trouble getting my Deltec CRRT 1500 calcium reactor to work properly. I’ve followed all the steps online and purged all the air from the system. However, I’m encountering an issue during the final phase of setup.

When I plug in the CO2 sensor and start the CO2, it doesn’t enter the chamber, and the water level doesn’t go down. I know there’s CO2 in the tank because when it’s not attached, there’s plenty of CO2 coming out and pressure in the hose. Additionally, when I use a bubble counter, there are plenty of bubbles being made.

After a while, the CO2 empty light comes on, even though the tank is full. I’m not sure what to do next. Has anyone else experienced this issue or have any suggestions on how to fix it?

Thanks in advance for your help!

I haven't used a reactor in a long time and when I did, I didn't use a controller/solenoid so, I won't be much help. But, I'll bump this so someone else can (hopefully) help. Maybe @wvned @kharmaguru @JCOLE @Reefing102 will have some ideas.

Honestly not certain but found this on Deltecs website about the alarm -

Sorry, never used anything like that.

Thanks everyone, I changed a few parts to new one on the reactor including the feed pump, flow sensor and the solenoid and it’s is working now!
