The Rena filter in GreenBean's 110G penthouse just died.
Need another filter and am trying to save as much moolah as possible. In searching for filters, most all of them are listed by their GPM and not tank size.
So for a 110G spa pool (for a single adult turtle), what GPM do I need?
Also, side question, most filters I see tend to be tall and skinny. Are there any short and fat ones?
