Hi everyone I have had my alkalinity tested today and its 2.8!!! I have bought some Nyos alkalinity + and I haven't a clue how to dose! My tank is a 300 litre tank with no sump. So I will have to do the pre mix solution but how? How do I measure powder in mls? Please help me. Here is a picture of dosage instructions. Also the website didn't help. Thanks indvance I really appreciate your help
