Well before i jump on carbon dosing got some issues... my phos is reading 0.03 so i may be phosphate limited when trying to carbon dose so im attemping water changes and reduced feeding to see if i can stay on top of it this way and then if it wont stay down try another method... but currently after another 4 x 20L today / last night my nitrates reading between 0-5 hard to tell with the colour shading with try my lfs's low range hanna tomorrow to get an accurate reading and continue to test to see how much and how fast they rise..
cheers !
