Scrapping the inline and going for NEO Diffuser

Hi all. First post here!

So I just set my my first 200L tank which is planted and during water cycle... I have the Proflora JDM inline diffuser and I am not really happy with it. The bubble counter is set up for 3BPS and the following its down to 1bps. I have to stay playing around with the inline diffuser to get it properly only to the next day it depletes. I was thinking of scrapping that setup and going for the NEO diffuser special. Does anyone here have it? Is it good instead of my inline?


Your opinions would be greatly appreciated!

I agree with Cortneybst that there might be a gas leak in the circuit. Soapy water sprayed on the connections as well as to the length of tubing and the unit itself will reveal leaks in the form of bubbles. Inline diffusers are generally more effective than the external variety, so it's worth the effort of getting this to work. If the body of unit itself leaks then it's defective and should be returned.

If you decide to go with the NEO then it's a good idea to place it under the filter inlet to allow the filter to help dissolve the gas.

Cheers,

The bubble rate has nothing to do with the diffuser, it is the needle valve on your CO2 regulator that controls the flow of CO2. If you are getting a variation in bubble rate, you may have a leak as others have mentioned above, or you may have a low quality/faulty needle valve.

Aside from checking the system for leaks as already suggested, also take into account that an inline diffuser requires a certain minimum pressure to work properly (e.g. 0.2 MPa). If the working pressure is not high enough you may get it to work one day and in the next day the pressure is just not enough to "kick-start" it.

Hi all so I think i found the issue.. The diffuser was positioned horizontally, as soon as I placed it facing upwards it kept it consistant. What I realised though is that the diffuser holds water in it.. Thought that when CO2 goes on it empties but not the case..

I saw someone mention this on another post too. It's my understanding that the chamber is supposed to be filled with water as it's in the outflow of your filter. The diffuser is just adding the CO2 along the way. If water didn't fill it the water wouldn't come out the hose.

Glad you resolved it though :)
