I've been cycling a new tank and started with a HOB Whispter PF10 filter. After realizing that the flow would be pretty punishing for my betta, I also muffled it and it works fine. I've been looking at the sponge filter and ended up getting one on a whim and decided to add it to my tank. Now I was thinking, should I just remove the HOB filter and rely on my sponge filter (which I now prefer), or should I keep both of them in there or.. are there any pros or cons to having both? Also, its still cycling (fishless cycling). Would having two filters in right now slow down the cycling process?
Any input or help is appreciated, thanks!
