Thanks for the explanation, it makes a lot of sense. I also find it interesting that there is not a lot of experience of the siesta being used in combination with CO2. I think I,ll have a go and see if it has better results than running the CO2 without the siesta. My CO2 is already on a timer, so it will be easy to add a few more timer slots to it. It might also help my CO2 to last a bit longer too!

Hi, I have the Fluval Plant 3.0 light on my 50 gal tank. I am gradually managing to get on top of the algae with small adjustments, but am wondering about the siesta method, but my question is this: I have a CO2 system in operation, so do I turn off the CO2 briefly when the light go off during the siesta, ie. If I have a 3 hour siesta, do I turn off the CO2 for the middle hour? I have livestock, mainly guppies with a few cories and neons. Thanks
