While I believe you can my issue with this whole story is…. I top off with kalk and use my dosers for all for reef and bacto balance! Now I have a big enough system that if the all reef dumped all 1000ml I’d have time to change some water and what not… on the other hand if my bacto balance dumped I’d lose my entire tank! Ugh… ain’t no way to detect a carbon source over dose to turn them off unless I can program “cloudy tank then off” haha!Couldnt you plug the dos' power supply to one of the outlets and program when ph > to turn it off?
