Diffusor or Reactor?

[tawauboy]

are you using pressurised co2 or diy co2?

Hi, I am a beginner at planted tanks. Started using a cheap taiwan brand diffusor 3 months ago. Now i am having problems releasing CO2. Not too sure what the problem is. is it due to algae on the diffusor surface? But based on what i can see, there doesn't seem to have any algae. When i disconnect the bubble counter from the diffusor, i can still see the bubbles emitting from my co2 tank into the bubble counter. the moment i reconnect it, the bubbles stop. I suspect there is some pressure that is stopping the release. Please, can anyone help???

Hi Boon yong, welcome to AQ.. I presume yr bubble counter is working rite? wat kinda co2 u using? DIY or cylinder? if its DIY, then the pressure isnt enuff to push the c02 out of the ceramic plate.. if its a cylinder then u better check, pressure built up has to go somewhere, perharps there is a leak somewhere... is the surface of the ceramic still the same color as the first day u bought it?

I am using pressurised co2

check for leakage then

The other thing to check is where you put your one way valves. If you placed your one way valve after the bubble counter, I would suggest you check to see if you placed it in the right direction.

Thinking of trying external reactor. How much will it cost? Any recommendation?

budget? taiwanese made is ard $15, the more branded will cost u ard $100

Simon, where can I get the Taiwan external reactor ?

In the case of the reactor, all the air seems to be dissolved.

So which one better? Or are they the same?
----------------

Interested in an alternative? I don't use reactors, diffusers, or airstones.



I simply took the CO2 line from my DIY reactor and feed the resulting CO2 into the base of an old powerhead. The powerhead's impeller mashes the CO2 down, and the resulting bubbles are barely visible to the naked eye.

The bubbles are so small they travel throughout my tank via the eddy currents. It's not uncommon for CO2 to travel and estimated 2 - 3 feet under water.

Nice things with this:
========================
1. Cheap to build.
2. No maintenance.
I don't have to clean this setup all the time.
The algae looks ugly, but DOES NOT effect the efficiency.
3. Very efficient - bubbles travel in tanks eddy currents.
4. Controllable.
When the lights go out, the powerhead shuts down as well (via a timer).
No powerhead means CO2 does not dissolve into the tankwater at night.
This is good because at night plants take in O2 and produce CO2.

That's my 2 cents worth...

scooby: clementi, petmart or any lfs selling planted tank accessories shld carry it

rthomas: nice

Wah... lawrence, your yamato comand kah... go inside the reactor. Won't the yamato get CO2 poisoning.....
----------------

My yamato goes into my denerrle reactor to eat the algae as well. The young mollies also goes inside too. So far no problem.

[little bear]

where to buy denerrle reactor? How much is it?

[LiquidFX]

I got it from Clementi C328.

It seems to have a fixed price of $110

[little bear]

So which one is better, cost effective. The dernerle one or ADA pollen glass?

[Simon]

reactors r more effective, but its not that great till, u can see the differences... for looks, I'll go for a diffuser (ADA)

[peterkoh]

I've using the UP 401 reactor and the bioballs have stopped spinning as CO2 fills up the space and push them downwards. I just let it remains that way as trapped CO2 slowly being dissolved by water pressure forcing upward. Why bother to remove the trapper CO2 ?

The only concern I have is waste buildup in the bioballs as I'm using a pumphead to direct the water-co2 mixture into the reactor.

er... pollen glass.. i think gen x should have... but about $100.... a reactor can be as cheap as $10....
i like the 'up' brand turbo-jet reacotr the best... damn good...

----------------

I have bought the one with balls, I think it may not be the same "turbo-jet" one that you have mentioned. Is the "turbo-jet" one come with the ceramic? It this equally efficient??
