Hi Guys, I recently installed a 1000L marine Tank and have just completed my cycling process. I was given a ater test kit which does Ph,Alc,No2,No3 and CL tests. Problem is that there are no instructions on the box. Anyone know what the normal procedures are for these tests? Because on the bottles there are just numbers next to a picture of a drop...eg on a bottle it will say the following No2 A 3Drops then another bottle No2 B 2 drops etc Can anyone help?
