nope...
its somewhat the same... diffuser just makes the bubbles finer... Finer means more solubility of the CO2 into the water... but if you find means of delaying the bubbles from reaching the sruface that should work as well... of coursei f its bubbling like CRAZY... what the heck.. you'll have your CO2 in pretty much excess... |

Maybe I can share a trick about using the diffuser. Normally when we start off we're all very Kiashu and place the diffuser all the way near the bottom of the tank, this way the bubbles will get max exposure while they are on the way up. For tank CO2 this may not be a problem, but for DIY CO2 whichi I am still using, it doess sometime cause some delay in the initial stage
So here's what I recommend. When you mixed your DIY CO2 fix up eveything and put about 5mm of water into the tube as a marker (anywhere where there is a connection), fix the tube into the diffuser but leave in on land, try to clear the diffuser of water before you fix it up if you can. In this way without the additional pressure of the diffuser in the water, you should see the water marker starts moving once you DIY CO2 generator start "cooking". Once the marker is moving smoothly lower the diffuser slowly in the water, couple of inch in at a time, there will not be bubbles for awhile until the pressure buildup in the bottle equal the depth. But if for too long you notice no bubbles forming, its means you sprang a leak somewhere. Hopes this helps. |

The bubbles produced are fine, so that are pretty good IMO. Thats provided you could get it to work Last edited by dragonfly_sg; 11-10-2005 at 01:50 AM. |

2)I use the cheap one from NTUC, the brand is bake king. Normally found in the baking corner for only about a dollar plus. The fresh (newly opened) ones are usually very effective but they tends to be less effective if keep too long or when they crust or harden maybe due to the high humidity. Wonder anyone else has the same problem? |
