Another liquid carbon question

[Mortis]

All 3 brands of liquid carbon (Excel, Easycarbo and AE) advise a higher dose when initially setting up a tank or after a large water change. This is followed by a recommended daisly dosing of about 1/6th that amount. It has ben mentioned that liquid carbon only lasts in the water column for about 24 hrs. If this is true then why isnt the daily dose higher and what is the point of the initial high dose ?

Its initially up to you how much you add.
The info on the bottle of fliud is only a guide.

Easycarbo state 1mls per 50ltr of water per day with a maximum of 2 mls per 50ltr with a heavily planted tank - i add 10 mls per day on a 215 ltr tank - there is no mention of an increase in quantity after a WC.

good quaestion and one that i have not thought about before. however, i have never taken those instructions and just gone with the daily dose from day 1 (no large intial dose), i do this with all chemicals.

I usually just add a large dose when setting up the tank initially but never add extra after a WC, just stick to the regular dose amount. Still it is quite strange why we are asked to do an initial large dose and then smaller doses
