Which Co2 Delivery system are you using

[illumnae]

Mist started appearing after I posted my last post, but drop checker isn't bright green, only bluish green and i don't seem to be able to increase the bubble count any more than current

assuming no leaking, it sound like not enough pressure

[felix_fx2]

before mine broke, i recall 1-2 sec 1 bubble.

Here's a photo of my solenoid gauges. It's showing 900/30, which should be sufficient right?

[felix_fx2]

not enough pressure, mine about double of yours 60-70 when idle.
that UP Aqua inline with 2 ceramic shaft need 36PSI, think indicated on packaging. You can try 1 shaft, should have lower requirement

I can remember what the requirement is it 36psi or 42psi working pressure? brand to brand also different

[limz_777]

anyone got a faulty metal check valve before ? recently mine got stuck , use a air pump to test , no bubble coming out , weird

up aqua "inline super diffuser" required minimum 36psi

Which solenoid are you using?

The Up Aqua one I am using is a single shaft one, not the 2 shaft one. This one: http://www.ebay.com/itm/UP-aqua-Inli...item5d41ba3210

Here's a video showing how slow it is:

I use this one as well. Becarefull on the CO2 nut, it break easily if you tighten too much.

It's not broken yet *fingers crossed*, but I'm not getting CO2 levels that I need from this system, so I either got to change my solenoid to one that works (which one works???) or go back to using a normal diffuser

Problem solved! It was the check valve after the bubble counter giving problems.

I think because it was "blocking" the high pressure backflow due to the inline diffuser, the "door" was slammed shut and CO2 was not permitted to go through the correct way either. This resulted in very high pressure within the bubble counter itself causing bubble count to slow down. Luckily problem solved - otherwise huge pressure in the BC may end up causing a mini explosion!

Just curious, did you change the check valve to another one?

[illumnae]

No I just removed it

No check valve? Wouldn't the tank water gradually flow back into your bubble counter when the Co2 is off?

[illumnae]

Its a long way to flow upstream. Filter is under the table and co2 cylinder is on the table (office tank). Also, I haven't encountered water filling the outside portion of the inline diffuser yet. There's also a check valve before the bubble counter to help maintain pressure even after the co2 is switched off.

Anyone recommend a check valve that works with the inline diffuser? The metal ones don't

[felix_fx2]

I use this, but i broke the screw 2 times. Managed to replace them with a brass screw from my needle valve on spare regulator set.

P.S: whats that part name, think i wanna buy a few more haha

[Shadow]

I use the same model, quite good although look bulky

[felix_fx2]

this is one of the few that have a nut to lock the airtube in place, bubble counter with lock easier to find.

Yeah, i noticed in your video the Co2 tank is placed above the canister filter, that probably prevents back flow. The Co2 tubing is really long too so it'll take more time after the system is off for any residual pressure in the tubing to dissolve and let the water back flow in, probably before that happens the Co2 system is back on again anyways.

Interesting observation about the metal check valve possibly being too strong in terms of blocking the gas flow... i guess different check valves probably have different levels of pressure tolerance.
