I like these filters but they are off the beaten path as far as the norm goes. My other filter is a Oase Biotec 18 (this is a Biotec 36), has done a great job of handling the Ammnia, and Nitrites, always zero, in my 3800 gal pond with 16 fish average size of 14". The problem I was having was I was feeding Hi-Silk 6-7 times a day, and the protein wasn't getting taken care of so the algee was blooming, the water always had a yellow or greenish tinge to it and foam on the surface. Also it was having a hard time dealing with suspended fines, as all I was using was a 4" bottom drain drawing approx. 3000gph, and a skimmer drawing 1300gph. With this new filter I am going to add 4 mid-level pick-ups, and a another 3400gph pump and split the draw from the mid-pick-ups and the skimmer to the new pump, which will all go through the new filter. The skimmer wasn't really being filtered before except for a piece of mat in the skimmer box and being returned to the top of the island in the center of my pond.

The nice thing about this filter is the water gets sprayed over the micro-screen, then the water trickles down over the sponges similar to a trickle tower, and out to the smaller chamber where Oase supplies the filter with Zeolite, but I am going to probably put fine malata in there.

I think I should have it whipped after that. All I can say is these filters do a great job, requiring a very small foot print.
