Sooner rather than later I hopeI know I should get a test kit sooner rather than later.
Good to hear the frags are looking better. Don't be afraid to do more than one water change weekly, you will improve things that much faster. Just be sure the water is well aged/aerated (24hrs) before use.I am going to do 15 gallon water changes weekly to try and clear some things up.
