I did a run down on what you need to get going with pressurised CO2 and I've got some handouts available that explain why CO2 is important (you can get these by emailing me at withdan@outlook.com).
Something I want to talk about here is how a drop checker works and why it's so important to have one.
If you don't know what a drop checker is then you didn't watch my video to the end...shame on you. It's a pretty dry video to be fair and was made to help a one or two people so audience retention is going to be pretty weak on it, you're forgiven. a drop checker is used to measure the amount of CO2 in your water column. It captures some of the CO2 that is given off and the pH indicator in the drop checker will change colour accordingly.
If you don't have a drop checker fear not I have put together a chart so you can work out how much CO2 is in your water, you'll just need to know the pH and KH of your tank, these are common tests that are even available on strips so they're super cheap (the liquid ones are more accurate). If you want a copy of the chart just email me at withdan@outlook.com.
