Already have one, just wondering what range to set the bpm at. The solution I have is a 4dkh and regent mix. It says put in 5 drops, this only covers a 1/4 of the ball, is this enough? though It would need more.
The colour remains yellow all the time. Currently running at 1.2 per second.
The dKH is in relation to ph with regards to CO2. Instance: if your dKH is 4 set your CO2 injector rate up until your ph drops to roughly 6.7-6.8 There is a chart that shows this correlation. It is best to use a ph controler attatched to your injector to regulate the ph as it will change with the time of day and other factors.
