my take,
I'm like the consumer reports for my customers. I buy whats new & try it out first before selling it in our shop because if its crap & I would not use it then i'm not selling it! Well I bought & set one up when it came out & placed it on a 110 with a trio of wild samazi fronts 6" size range, group of 5 Placido phenochilus & a couple scanvengers. It went 14 months before the first cleaning! Yes the bio load was not heavy but I like the filter myself & it worked very good & is well made. I used coral chunks, bioballs, bio chem zorb & some floss pads within mine. Going on two years & not a problem or with the many I have sold. I have one customer that has bought 4-5 already. One guy that helps me at the shop at was having problems it spitting air & little noise but redid the media placement & it to take care of it. I also know if you use the fine filter pad which works really well but it clogs much quicker, then filter needs to be clean as such. I also put one on my 350 gallon at home along with a 500 gallon wetdry system & I now get a extra week or two before water changes. I have a xlarge drift wood piece which tainted the water some, but with the biochem zorb the water is clear.
Remeber your media selection can determine how it filters & for how long?
I use some of the ehiems & have sold them & used them on maintenance accts & they do work well, but the newer hagen line i lean towards because of ease of use & they move water more.
Also I did try the new Marineland 360 can filter & it also is working well & doing a good job for over 6 months now with one cleaning.
I think the magnums are going to be discontinued soon? The penguin filters are being eliminated also. With two major players that own half of the industry they have product competing against their own line so we will be losing some of our options/choices of filters etc. out there.
