Ive just mixed my first batch of all in one going by the article on here, ive been dosing 1.75ml daily and do at least 1 50% water change weekly, does this sound right, the tanks drop checker is always light green but its only got three 9W PC bulbs giving a total of 27W of PC lighting and the tanks only 8 inches high, so ive no idea how high the lighting really is, its also got sera substrate.
