i recieved my rhinox 5000 diffuser today and i set it up with my dennerle comfort line 250 kit.

co2 bubbles arent coming out yet i have a few q's

!) the diffuser is half full of water should it be full up or empty (the bit inbetween the bottom and the ceramic bit)

2) i removed the bubble counter as it cracked is this a problem.

has anyone else had this problem

Wolfenrook is right, I'm sure if you increase the pressure on your regulator just quick then the bubbles will start flowing nice. Then all you got to do is lower it back down until you get the desired mist of bubbles.

A diffusor should release bubbles even at the lowest of low pressures. Would just take a lot longer for it to build enough pressure and after that the output would be low. Sounds to me if has not given any bubbles that there is a leak somewhere.

I use a Rhinox 2000 and after cleaning and reconnecting (zero pressure) It takes about 10 secs before mist starts.

As said above a bubble counter is nothing to so with the process. Its just as a visual counting guide.

I would check your hoses and connections (and cylinder output pressure gauge to make sure that something is coming out!!.

my diffuser is the cheap knock off of the rhinox off ebay it has water in it..

i turned the pressure onto full nothing...
disconnected everthing then connected it again nothing still...

could it be something to do with the check valve maybe blocked ? i m quite desperate for it as theres p-lants in there but no co2...

Firstly check the gauges. Is the cylinder pressure at 50bar or above. then check the output gauge. If you are on full then this could be in the red and dangerous.

If these are both reading positive then move to the next point as stated above. Is the solenoid working. Turn it on and off with your ear next to it. You should be able to hear it click as you turn on and off.

If you have your NRV the wrong way round or it is blocked then it will either move eventually OR you would've already had a burst hose.

Finally the diffusor. Yes they are meant to get water in the bowl. Some people use the diffusor as a bubble counter in itself although don't go by the 1bps start guide as the bubbles will be much larger. More likely 6bpm would be a better starting point.

Just as the ceramic pores let gas out, they let water in. If you were running 24/7 CO2 and started it up straight away with no water in the diffusor then you would most likely not get any water coming in. Works with water in or not.

If you can't find a leak in your hose then the diffusor is bust!!!. For leaks water some washing up liquid down and spray it along the route---> reg, solenoid, hose and any inline attachments. If there is a leak you should see some bubbles wherever the leak(s) are.

If all the above is positive including gauges, solenoid and hose then it has to be the diffusor.

Sounds like you bought a duff regulator, or the needle valve is a duff one. Try connecting a line directly to the needle valve and see if anything comes out. If not then it's definitely one of the 2, so next check would be to see if any gas comes out of the diffuser with the needle valve removed, if it does then it's your needle valve, if not then it's your regulator. If they are both fine then check your solenoid (if you have one), and then your check valve.

It's pretty obivous that at least one pieve of the setup isn't working.

ive nailed it down to a duff reg and needle valve however i cant seem to find a place that sell the dennere ones for this kit (dont want to change the thread either) anyone know a place to buy these there for the profi 250 set.

also there is no hissing sound when i attach the reg to the co2 bottle on its own.
