I have had fish for several years. At the start i was all into checking the levels and once i stopped killing fish i kindof stoped bothering. If it aint broke.... Anywho with all the reading i have been doing i got the test kits back out. I noticed my 55 with no plants and one piece of drift wood has a ph between 6 and 6.4 similar to my tap water. My 20 quarentine however has a few plants no drift wood and a ph of 7. My fish all seem somewhat fine but seeing as how i have actualy been using the quarentine tank to introduce new fish i would like to minamiz the shock. any thoughts?
