I would not do daily. I have been using this product for six years, and you should dose once a week, following the water change, with the amount specified for the tank volume, or close (remembering that a 55g tank is not holding 55 gallons due to substrate, wood, etc). A 98 litre is approximately 25 gallons, so you likely have 20+ gallons of water.
For 60 gallons, 5 ml, and this in half is 2.5 ml for 30 gallons. A half teaspoon (the measuring spoon as in the kitchen) is 2.5 ml, so I would add this once a week. I follow this in my 20g which has a few plants. I don't know how exactly the nutrients are mixed up in Flourish Comprehensive, but I wouldn't go lower than this. And give the bottle a bit of a shake before using each time.
