To me, moral of the story is if it ain't broken, don't fix it. I have never used products that guarantee crystal clear water as I know that at the end of the day, it all depends on the filtration. About Petfran products on the other hand, I try to stay away as I trust more seasoned companies who have been in the industry for a while. I had a bad experience using their pH pen as the reading is far from accurate. I actually used a Sera Test kit and a Pinpoint pH meter to confirm the readings and they were world's apart.
