Hey guys, the reason I asked GPH recommended for the Johanna is because I have been studying Discus, and they require 1 - 2 cycles per hour. Compared to marine which is 10 - 20 cycles per hour depending on corals. For the Johanna should I run 4 -5, or even greater? Also, the sevs, you guys recommend only 3-4? Are they large waste producers?
I still plan on 50% water change once a week, if not twice. I just feel that 3-4 is odd, 5 for shoaling fish is what I am used to, makes them feel more comfy, plus helps spread out tension. I have so many ?'s, are there any books on crenicichla, or r u guys they only way to really find any info?
