I have many aquarium set ups and have used chlorine removers. not good you are better off ageing your water. there are things that they add to removes the chlorine that quite frankly you dont want to smoke and I have read that add salts to the water that will increase the chance of nute lock. (luv you bro) but you are way over thinking everything. not a bad thing but just try a basic grow first and go from thereI know things have turned south on you before so just put some seeds in the dirt and see what happens then go from there. dont just try to learn everthing all at once. Im sure that anyone here have had several different outcomes while learning to grow this stuff so I feel trial and error are the best teachers and advice from here is a grain of salt.( abig grain of salt) as we learn so does everyone else. AND YOU CAN TAKE THIS WITH A GRAIN OF SALT
