Hi everybody. I'm still learning a lot about bettas, and right now I have a 10 gallon that I am cycling. I will be adding a giant betta in there when it's done (of the batch of the babies I'm getting tomorrow...eep!). Anyway, I am coming at this from the viewpoint of someone who has done tropical community tanks for about 15 years, and I'm confused by the differences there are between that and betta care.
My question is: do I need to have 2 filters on my 10G? Right now I have a whisper 10i and a sponge filter (rated up to 15g). I have always tried for 2x filter capacity above manufacturer ratings, i.e., I have filtration for 120gallons on my 55g tank. However, that 10i drives me nuts. Although it's turned down, it just causes too much disturbance when combined with the sponge. I don't want to stress the fish out. Could I ditch the 10i and just stick with the sponge? I have bulk carbon, and I can and do make "filter bags" of that to float in the tank when needed.
Also, the betta is gonna be a HMPK giant. With the shorter fins, is flow as big of an issue as with the veils and other big finned-types?
Thank you. I feel like I have so many questions. Thanks for bearing with me.
