Yes, I'am well aware of that. But how much can shift the ph in a short period ( 2 to 6 hours ) the humic acids from woods and the rest of chemicals to induce a high fluctuation in co2?
I've done a little experiment, co2 was on direct injection at a 1,5 bbs/s and the controler was only in "measure" mod. The fertilisation metod is daily in a small amount, with the help from tests. Results, the ph oscilate from 6,45 in the mornig to 6,85 at 9 pm when the light turn off. And the visual co2 test show that too. So......
Which way is corect?
SN. Now the rate of co2 is apx 1,8 bbs/s in a 180 liters ( 47 gallons ) aquarium and the time of injection is in the day time half hour on and an hour and half +- 15 min off, in the night is 10-15 min on and apx 2 hours and half off. The visual co2 test show a constant light green. In the test i use the fluid indicator and a 4kh water ( osmose and Baking Soda ).
I have 2 years + in that hobby with a lot of documentation and experimenting, do it with a lot of plants and configurations.
