AC is considered one of the best HOB filters. you could run 2 70's on there or just pick up one 50-70 and keep the topfin..
also pick up an extra ac sponge .. cut an X in the top and slip it over the intake.. it will work as a pre filter and will also work as bio media. it will also help slow down accumulation of detritus that is clogging the top fin.
check out dr fosters.. they have bio filter inserts that fit several brands where you can change out the filter and just run sponges.
