I purchased it about a month or so ago and it works great! my amonia is always low now! i have it on my 55gal and the filters handles 100gal max. my water quality is always good too oscars colors are alot brighter as well im assuming do to better water quality.. but just thought i would let you guyz know if anyone was looken at this filter

they don't sell those over here in the UK, however, just had a look and they don't look too bad, good luck with it

i use a magnum 350 on my tank. the only drawback i found is the lack of area for the biological media.i have a wet dry to cope with the bio so for me it is used for water polishing and mech fitration. all in all i find it an awesome filter and im sure you'll love it
