Any equipment to inject CO2 into the tank without using diffusers?

[RonWill]

Yes, will be using a solenoid (specific model I'm using is: "ANS CO2 Electro Magnetic Meter Type A [Solenoid]") in place of a manual regulator

Solenoid and regulator are two entirely different animals. A regulator is that mickey mouse thingie with 2 big ears (pressure gauges) while the solenoid is what attaches to the regulator. One either use a manual fine tuning attachment or a solenoid but neither displaces the use of a regulator.

I have this thing (& a CO2 tank):



which I believe is my solenoid. You mean to say, on top on this I need to get another item called a regulator?

[RonWill]

duh... somebody please hand me a shotgun...

Ralliart, nope. One regulator is all that's needed. What you show in the image is complete (as far as basics go).

For reference.

Co2 tank - regulator - solenoid - needle valve

What you are showing beside your razor mouse is regulator+solenoid+needle valve.

Regulator is with the 2 meter things to show the pressure.
Solenoid is the one with power. (aquarium is NC normally closed. Aka no power on closed)
Needle valve is the one you pinch and tune. I love this part

Haha...sorry, I'm really very new to these stuff; expect more "stellar" questions from me in the near-future, as I begin setting up my tank.

Thanks for the verification.

Visually, where's the needle valve thing in the photo, if I may ask?

...Solenoid is the one with power. (aquarium is NC normally closed. Aka no power on closed)...

In other words, the solenoid component will not consume electricity after it has turned off the supply?


Anyway fellows, I guess my confusion stems from the fact that in some literature, "manual regulator versus electric/automatic solenoid" is almost mentioned, leading me to believe that going the "electric/automatic solenoid"-route = no regulator (I didn't know it includes a regulator as part of its component-chain).

[felix_fx2]

That's my favorite section!
The part you turn to control how much co2 exits...

Now it is called needle valve with a reason, inside is needle shaped.

The solenoid yes no power used when off, we control power going to it via a timer. now a timer does use a tiny bit of power but that's unavoidable.

I add some info on your pic, hopefully it help you to understand

[felix_fx2]

Thanks shadow.
Office busy didn't have time to edit pictures.

Yes, it does. A lot. Thanks. Actually, the "auto regulator" portion, is it in essence still a manual regulator with "automation" derived from the mounting of a solenoid?

& I didn't realize that "nuts" portion is actually a (needle) valve.

[Shadow]

no-no-no the auto regulator mean there is mechanical inside that regulate the pressure. It mean reduce pressure from 1000psi to 20-50psi and automatically maintain it.

Manual regulator on the other hand do not have such feature, thus the output pressure is unstable. You probably heard many people using manual regulator complaining about always need to adjust bps every time. This is because you are trying to output couple of bps from 1000psi. It is very-very hard.

[felix_fx2]

No worries, in the past I had no clue why the name until I chances upon diagram showing how it work.

Thanks for the wonderful elaboration.

if you really want to use the impeller to "whack", you can try using eheim compact+marine, just need to supply co2 into the air inlet. http://www.eheim.asia/prod_pump_compactPlusM.html

That's interesting; may I know which component in this "pump" whacks the CO2 into even finer bits?

[Shadow]

needle wheel, you can actually modify any pump and DIY needle wheel impeller.

[madscientist]

Shadow is right. You can see a picture of it in that link, the white wheel with spooks

[madscientist]

Make sure you seal tightly the skimmer though in order to trap undissolved co2. The undissolved co2 will somehow, hopefully, dissolve over time.

Saw a video of how these pumps with needle wheel perform:



I can't stop laughing after watching this video; I don't know what will happen if there are fauna inside & I deploy the pump like this, i.e. "gas-gas-gas!!!"

[Shadow]

you cant even see inside. Your plants will probably die though, the bubble blocking the light.

[madscientist]

Haha, that's why I deployed it with a protein skimmer?
