Hey everyone! This should be a pretty simple question for you guys, so I was wondering if I could get some help. I have a 37gal freshwater tank, that currently has an Eclipse series3 all in one hood and filter system. Tank looks good the fish have been doing great for over 2 yrs now, but the light fixture is crapping out on me and no replacement parts are available since the unit is discontinued. I am wanting to switch to a Fluval 206 or 306 cannister filter with a regular aquarium hood. If I run the fluval in conjunction with the current set up for a few weeks, will it take care of any cycling issues I would have if i just swapped filtration immediately?
