I like canister filters on some tanks. They are well known for being nitrate factories if not cleaned somewhat regularly. All the stuff builds up in the filter and creates nitrates that would be completely removed by a filter sock that was changed out weekly.
I don't think you understand why he said they were inefficient energy wise. It almost seems like you put no thought in your reply. You can't just compare two pumps with similar flow rates then boldly state efficiency with energy argument debunked. You might have noticed there is more to a sump or any filter than the pump. You can take the 1262 pump from the 2262 or the mag drive 9.5 and combine that with a 40 gallon breeder, 15 gallons of substrat pro, matrix, or biomax, and a filter sock and have a far more efficient filter comparing energy usage with the filtering results you get. I realize that you have to change a filter sock that makes a little maintenance, but if that's too much for a person they probably shouldn't be keeping fish.
