I used to use the bettarelex. Attached photo is my tanks set up.
Each tank have filter and it comes with active carbon inside filter media.
First day when I put the bettarelex, the tank is yellowish. But next day it become clear water. My bettas are happy in both with bettarelex or clear water.
And I worry if I keep on adding bettarelex, active carbon will absorb all and release some poisoneous chemical again after sometime.
But I need advise that should I remove "the carbon filter and add the bettarelex" or "with carbon filter and clear water without bettarelex".
Which will be the better option for my betta?
