I've got to treat my tank for internal parasites;( Does anyone know if BGK or plecos are particularly sensitive to Levamisole HCl?
Huh? Where did you get this info? Beneficial bacteria do not colonize the water column therefore, water changes are hardly the issue.macmilan;4372551; said:did the meds recomend changing that much water? if so its a waste of time changing that much water can completly wipe out your tanks benifitial bacteria, i hope you have hardy fish!
