Hi Island lad , Thank you The DIY Co2 is stable for 4-5 days after that it slows down and does not keep the bell full of Co2, So i change on day 5 all going well so farCracking tank mate, really lush and healthy.
How have you set up the main lighting.
Also do you manage to keep the yeast co2 stable ? I struggled with mine and had algae outbreaks so I went with liquid carbon. I may try the two and give your recipe a go.
