Free C02 regulator
And you can't believe everything you read because it was written in a book.
So Sir, that is my opinion. -- Bob Alston bobalston9 AT aol DOT com "Kris" wrote in message news:lcyqc.19952$0e6.13211@clgrps13... Sir Douglas Cook wrote: Quoted from the book: "C02 injection. In recent years some aquarists have used this process, whereby carbon dioxide is added (from a gas cylinder) to the aquarium, in order to promote plant growth. CO2 injection must be used with considerable care, if at all. Remember that high CO2 levels may reduce the oxygen uptake of the water and lead to a risk of hypoxia in the fish, especially if the aquarium is crowded and /or the fish include species with a high oxygen requirement. Some aquarists try to get round this problem by using additional aeration, but, while this will certainly increase the oxygen content and benefit the fish, it will at the same time drive off the carbon dioxide, making the CO2 injection a rather pointless exercise! CO2 injection should always be turned off at night - When the plants do not need it." While I do not wish to enter into a debate with anyone I think there is another important factor that has been missed CO2 injection reduces ph by turning on and off the injection system you may be causing ph swings that could greatly harm your fish Kris --- Outgoing mail is certified Virus Free.
