Amount of water inside diffuser affect CO2?

Hi folks.

This might be a stupid question, but i can't figure it out, nor can i find anything on the forum.

When i do my weekly WC, i soak my NEO diffuser in a water/bleach solution in a glass on the floor for maybe 30 min. Before the soak, it's usually filled with water, but after it's completely empty. After a day or 2 it's back to normal.

My question - does this affect the amount of CO2 diffused into the tank, how fine the mist is etc? Because of a difference in pressure or something?

I'm asking because i think i'm having some fluctuating CO2 problems. Hope this makes sense

thanks and have a good day

Well it is not really empty... it is filled with air, right?

So I would assume it may take a couple of hours or a day until that air is replaced by CO2 again and for that time, CO2 levels may be a bit lower.

Does that make sense?

Could you fill it with water before re-connecting it?

(I am not too familiar with that particular diffuser so I may be talking through my behind and can safely be ignored)

Yes it's filled with air afterwards, but no water. It usually takes about 1 day or so before it's filled again, and as you mention, CO2 levels might be different in that time - and that's what worries me, because that makes the CO2 levels fluctuate troughout the week.

I can't fill the diffuser by taking the disc off unfortunately.

Thank you

Shouldn't affect the amount of CO2 other than maybe initially when CO2 first comes on in the form of some small delay. Water/liquids are not compressible. So when full there will be less space inside to fill with gas before pressure causes it to diffuse through. When empty there will be more space available to fill and pressurize before it starts to diffuse. That's the only difference I'd think that it would make and you're talking about a relatively small space so no big impact. The only effect that you'd probably see is that it takes just a little longer before it starts bubbling.
