Honestly , I doubt Lillie has any idea what gender Nebby is , she probably just assumes it ' s male plus it helps get her point across better , would feel kinda awkward her saying now get back in the bag lady or something <| sep |> Im that ugly goblin that lives in the sewers . <| sep |> Didn ' t you hear ? Douchebags aren ' t wrong in being absolutely douchebags . Other people are wrong in not appreciating douchebaggery . <| sep |> and then you sit there thinking welp , now what ? <| sep |> HIGH POWER OFF THE CHART ! !! Ceterum censeo uspez esse delendam <| sep |> I ' m not an expert on this kind of thing , so it ' d probably be best to get a second opinion , but I suspect a four foot intake tube on a HOB would present too much retrograde pressure against a pump designed for lighter duty and cause it to cavitate . You ' d probably burn out your HOB motor pretty regularly if you tried it . Plus HOBs usually aren ' t designed for this kind of aquarium form factor , so I ' m thinking a HOB is kind of a square peg for a round hole , in this case . As for canister , I tend not to use them in my aquariums since they don ' t provide much utility during poweroutages , but I do have a Penn Plax Cascade 700 which I absolutely adore . I ' ve used it on my 55 for years , but it ' s only rated for about 200 GPH . I suspect you will need more , because your pump will need to work pretty hard if you keep this thing at ground level . The SunSun HW 303 B seems highly regarded around here , has a much higher flow rate , and even comes equipped with a UV sterilizer the bulb would need occasional replacing which could significantly reduce the amount of manual cleaning you have to do . You could always place the canister filter in a cabinet a foot or two above the aquarium top and run the hoses that way fewer bends will allow you to get away with a lower flow rate .
