Re: polyguard, ich and more
Before you begin to treat with PolyGuard make sure to remove the other medication first. The water changes are good at removing medication and activated carbon is good at removing medication from the water.
Raising the temperature will help to speed up the life cycle of ich. You can do water changes as part of your normal routine, but it is not necessary.
As for the age of PolyGuard, there should be an expiration date on the bottom of the tube.
You may want to try adding some Gold Salt also to help with any stress and to change the salinity to have more of effect on the parasite to help kill the parasite or so it does not reproduce at an alarming rate. Add about a tablespoon of salt for every 5
gallons every 12 hours three times. The salt additions
will not ensure treatment of ich, but Gold Salt can be a good addition. Here is a link to Gold Salt;
