True also. All types of low-cost solution has it's own pro & cons. Therefore is up to breeder to pick & choose the most suitable system for them. Even now with a couple of extra tanks, I'm starting to complain about the weekly water changes routine.
Anyway I found out that even with filters, you still have to do a 100% water change after a couple of times partial water changes. I know now what's causing the death of my guppies.........
