Diffuser In Shrimp Tank

[Andy Woo]

Hi all AQ bro , which is the best location to place the diffuser in my new shrimp tank ? Please advise me . Thanks !

[veggie]

Should not be a problem. It up to your likingas long as not near to your air tube if you are using air pump.

Hi,
what's happening if the CO2 diffuser is near to the air tube? What difference does it make?

[Matt]

They may turn into CO3?

[mincedmeat]

Highly unlikely that CO3 will be formed. CO2 only reacts with the single 'O' atom and and not with O2, since both CO2 and O2 contain enough charges for it to be stable enough, unless chemical reactions are applied to the structures.

I am using a canister bro ,any problem using a canister ?

[newlife]

Placing of your Co2 diffuser at any location should not be an issue...

But try to observe the Dosage of Co2 into shrimp tank....as it will affect the pH.

CO2 injection is not an issue if its not too much and also plants are there to absorb it... if you are using a canister, you might even consider using inline diffusor or inline atomizer...

bro newlife, i think the affect on PH is not drastic to the shrimps.... should be quite minimal... in order to bring down PH a lot by CO2, i think will need quite a high injection which the shrimps will die of CO2 intoxication and not PH i believe....

Yeah. Agree. That explains for my "?" there as I am querying on the possibility that it'll become CO3 since it was advised not too near to air tube. Or is it because that CO2 will harden the tube?

I thought if CO2 mix with air will dissolve By it? Correct me if I am wrong,cause I am not a planted guy. Sorry to give out wrong info.

Noted , any recommendation of the dosage for 3 ft shrimp tank bro ?

[Ecalyte]

Why you don't want to put the CO2 next to an air stone is because it becomes completely pointless. The CO2 will get pushed out by the aeration almost the same time it's put into the water...

If you must have CO2, then put it at the opposite ends of the airstone, but try to put it in the path of your filter outlet..

[Andy Woo]

Bro Alvinchan80,what is the purpose of this inline diffuser and inline atomizer ?

[cheetf]

I believe that the reason not to put it near the airstone/outlet would be that it is actually counter productive. You want the CO2 to stay as long as possible and be as small a bubble as possible in order to dissolve in the water. If you put the diffuser near the airstone for example, the CO2 exposure time will just be minimised as it is quickly carried to the surface and released into the air.

[alvinchan80]

CO2 will be based bps (bubble per second).. Previously for my 60x45x45 tank, i am injecting 1.5bps to 2bps... shrimps are still fine... but of cause, I have quite a lot of plants inside to absorb the CO2 in the water.. But most important has to based on the reading of CO2 checker... Please ensure that you have a CO2 checker to make sure that the CO2 in your water is not too much and not too little...

Bro Alvinchan80,what is the purpose of this inline diffuser and inline atomizer ?

Inline diffusor or atomizer only prevents you placing the diffusor or atomizer inside the tank.. and the co2 'mist' will come out of your outflow (rainbar, jetpipe or lilypipe, etc... they have to be submerge in the the water to prevent lost of CO2).. i prefer inline because its attached to your hose... difference in diffusor and atomizer is that diffusor has bigger CO2 bubbles, and atomizer is misty but need higher pressure to push the CO2 out...

Putting it simple.

Air stone : promote/diffuse o2 requires by fauna into the water.

Co2 diffuser and variant: promote/diffuse co2 requires by plants to make food (and grow)

Diffuse or rather dissolve, is easier when have more "surface contact x time in contact"

I hope not too hard to understand.

Ecalyte in essence is correct. We want co2 bubbles to stay in the water as long as possible.

Thanks bro for the elaboration. now I understand and believe TS will as well.

Simple and easy to understand explanation of the matter!
