i'm planning on getting a sponge filter (max 20g) for my 10g betta tank, which will house a single male betta (and maybe a few nerites and cherry shrimp in the future). but i also have a leftover top fin silenstream power 10 hob filter from a 5.5g kit i bought (never had any problems with it despite all the negative reviews). should i put both of them on the tank for a single betta in a 10g, or just stick with the sponge filter? i know you can never have too much filtration, but i think bettas prefer low flow, and an added hob might be too much for him. (i was also thinking about putting both of them on initially to hopefully maybe speed up the cycle, and then taking the hob off once the cycle is established or a week or so after the betta is introduced to the tank. thoughts? note: the hob has been sanitized and does not have any bb.) thanks! edit: i just realized that the sponge filter is kind of massive. they also have a small one that filters up to 10 gallon tanks.
