Hello, so, I have a 20 gallon tank with a Marineland penguin 150 bio wheel that I'm not overly fond of. I keep having issues with reduced flow, the wheel not spinning, noise, having to clean the propeller...etc. So I was thinking about switching it out with a Fluval or something like that. How exactly would I go about doing this ? Could I simply run both filters for a few weeks, then take part of the filter/wheel in the already established filter & place it in the new one, let that run for another few weeks, then eventually take out the bio wheel ? Or what ?
