I maintain my regular weekly water change schedule but make sure to also maintain the full concentration of meds in my tank after each water change. For treatments that call for more frequent water changes I follow their directions. I would not go weeks without a water change or you're potentially looking at additional issues in connection with degrading water quality in the tank.jpbdh4 said:Seems like a long time to go without some sort of water change with an overstocked tank, even with mindful feeding and ample water agitation.
Agreed. During my years with south americans I've found that in most cases keeping the tank environment very 'clean' certainly aids in recovery, and for some is all that is needed for full recovery.DJRansome said:Or...if your max before a water change is 20ppm then skipping a week only gets you to 40ppm which may not be ideal, but is also not going to cause additional issues.
Also an argument not to overstock your tank (beyond what is necessary to manage aggression).
