Well if you dose 1/2 which is almost the same as exel. 1 cap is 5ml. You doing 1 cap per tank or split? 3785Ml in a gallom. Easy math... although you might consider upping the dose 5ml of excel in a 125g is light. I dose 1ml per 10 gallons of actual water volume.
Bump: Actually the 2l cap might be larger check with measuring spoons
