Ohh and you asked if waste away works?
It absolutely works very well. My system calls for about 7mL.
I dosed 2mL the 1st week.
4mL the 2nd week.
7ml the 3rd week.
Left skimmer running with top off to overflow. Used to run an air-stone with it, but now I don’t. I don’t even turn off the skimmer or keep the top off anymore. Some will be skimmed out, but I have enough bacteria in the system that it doesn’t matter.
The water gets clear after you dose like dosing LaCI3.
