ato dose

Used for 2 years, on shelf for 2 years. Ship or pick up in California 95121 bay area

I have a full 40 breeder I’ve been dosing by hand every day kinda over it, I have an apex that I’ve set up and wouldn’t mind the DOS system however I dose 3 part and it’s not worth abs extra 270 for me to get a second as nice as it would be. What does everyone recommend, any input is appreciated...
