Hi. I'm new here and so happy I found this site! I have a 20-gallon tank with a betta, guppies, Corys, and some plants. I have a question about ich medications, but first, this is what I'm currently doing. I am using Jungle ich tabs but am almost out. I live about 45 minutes away from any store that would carry ich medications. I ordered API Super Ick Cure which will be here today (ich-x would take too long to get here). So finally, to my question. Can I do a 50% water change and safely switch to the API Meds? Thank you for any help you can give me!
