I got a tank to fill a corner, its a 30 gallon hexagon. My question is since the water/air surface air is smaller than a regular rectangle tank, should i use a bigger power filter, like one that is made for 50 gallons? Also will i need an aerator?
+1 on the whisper there awsome and quiteId say go for the 40 gallon filters from whisper. These filters are quiet, and in my opinion the best. Most tanks need an aerator, some dont use them but I believe they help.
