Default Re: An (excited) word about filtration

I saw a comparison study of flow in gph on the net between filters. It said basically that when you add right angles and such and don't use the assumed head height you will not get the same gph. It also said that all pretty much all the filters except the Eheims were rated empty without media. The Eheims were true to the average ghp rated but of course all were tested new and clean.

Your article was quite interesting...
