I just recently purchased the aqueon 29 gallon deluxe kit. Im not sure exactly what filter came with it (between a quietflow 20 or 30). I added a new fluval aqua clear 30 to run alongside the quietflow. Today I discovered that this filter is LOUD and I was wondering if its okay to set one filter on a timer while I sleep then turn back on in the morning and keep the quietflow on 24/7. Will turning off the filter for an extended period of time prevent or affect biological filtration? Thank you all in advance.
