Hello everyone ! I'm new to the forums although I've visited plenty of times to get information.
I just moved my betta from a 2.5 gallon tank to a 5 gallon one (has his picture on the pictures thread).
Question is - I'm still using the whisper 3i filter that I used on the 2.5 tank although I upgraded the external pump to one rated for a 10 gallon tank or filter and It did seem to make the filter and flow more powerful.
Anyone has experience trying this if its good enough? If I have to get a new filter, any recommendations? Preferably one I can just get from the pet/fish store.
