i have a Deep Blue 45 that I am using for fish qt. I like the larger format, but still reasonable gallons for QT stuff. The rim around the top is pretty thick (about 1.25”). Insert a series of jokes here. I was checking into the Aquaclear filters for they were getting good reviews and people like the flexibility of the filters and media. Again, just for QT. However the 50 and 70 model don’t fit. Can only handle an inch, insert your favorite joke here. Any HOB filter recommendations for qt?
