Just how much CO2 should you have in your tank?

You want to use as much pressurised CO2 in your tank as possible without causing distress to your live stock. CO2 will make or break your tank and I want you to give you the confidence to use it as it should be used in a high tech CO2 tank. In some cases your CO2 levels will be A LOT more than you think. If you have no live stock you can really have some fun and crank it up. You’ll be amazed at how well your plants will do when you’re let loose…

Most of you are using drop checkers now which is great and just what I have been advising. But many of you get too hung up on the colours – remember the colours are only indicating a pH level change (they don’t really measure CO2). However when your drop checker is showing green (pH of 6.8), you ‘probably’ have good CO2 levels, but I would like you to take it one stepĀ  further because in some cases your drop checker may need to show yellow. This is fine as long as your fish/shrimp are fine. If they’re showing any signs of distress, lower your CO2 levels.

You really need to maximise the amount of CO2 you can pump into your tank so it will take a bit of playing around but the effects are tremendous and your tank can look like the inside of a champagne glass.
