Hi,
I have a 30l nano that I have planted with Crypts and moss growing on wood, I also use co2 at a low rate of 6 bubbles a minute.
I want to remove my internal filter and use a HOB to give more space in the tank,so as I can use more plants but I want to keep a good circulation to distribute the co2 properly.
I've never had a HOB so I'm not sure if they are good at circulation so I would like some advice from people that do filter their tanks this way.
Thanks in advance.
