hi guys
recently it just occurred to me that i can interpret the dosage on additive bottles in 2 ways.
say for eg it says:" use 1ml per 100L"
does this 100L mean 100L of aquarium water? meaning (total VOL of tank, X - vol taken up by Sand and LR, Y = vol of water in aquarium,Z) then take the final result, Z/100 and dose
OR
just take total VOL of tank and dose? meaning just take X/100 and dose?
it maybe a dumb question but i want to clarify this because it makes a difference between severe overdose, and underdose
hope to hear some inputs!
