All the guys I know that doses this stuff , are 1000% happy and never switched back lol . I have to try it out myself soonOk, guys, completing few last pieces for extended absence. Since I am using 100ml of each AquaForest 1,2,3, my dosing containers only last me about 15 days. So, I bought an extra set of these and turned caps to accept my dosing line. Will switch to these containers whenever travelling for longer than two weeks.
