Well it runs ok when the co2 is on, when the co2 is off at night the noise is unbearable water running sound and wurring. I've put two no return valves on the co2 tube to make sure nothing travels back to the reg. If anyone has,any ideas please let me know as I've ran out.
If only I saw is thread last week I would of got 2. Im using the new model of the up brands from co2art. Works great but its a 7up in my tank
