Dear Lary n others senior member I'm planning to add some more biologic filtration since friends of mine told me I don't have enough one. what do you think about my pond: pond volume 20 Ton, filter chamber 7 Ton, 50,000 bioball (some of them in trickel tower) and 50 litre K1 1st chamber is vortex, others bottom up flow.. water pump 200 gpm 2 HI blow 80 (1 in pond and 1 in chambers) If it is not enough I wanna add some more but I'm confused which one to choose? 1. Bacteria house: I'm affraid about turn over rate it need. my turn over quit low and can't increase cos don't have large enough pipe 2. Lithaqua, How about life time and how much we need? my dealer said 200 gram for 1 ton. I hear russel said much more than that the price here is about $E86/pail (10kgs).cheap? anybody tried compare BH and lithaqua? perhaps with the same volume/cost (BH with low turn over rate)? rgds, koihaku

The only pricey products in my filtration are the pump and the lithaqua (thanks Russell, love the stuff ) If I had the bucks to do it I'd probably have a K1 moving bed and BS to go with it. I've just heard too many rave reviews from people who have them established. As for me and my fishies, we get by with this. The pump (wardley 8500gph) with strainer basket feeds the vortex which feeds the crossflow tub with matts and 1 bag lithaqua, which feeds the lower waterfall. App 40-50 gpm. It feeds the other 90-100gpm to the trashcan showers full of bagged lavarock and lithaqua at the head of the stream. Results??? Ammonia, Nitrite, Nitrate... 0.0 ph stable at 7.8-8.0 And no pea soup in spite of several rainshowers mingled with hot sunny days and a pond with no shade . And no, I don't have any UV or aerators running . The water is Oxygen rich from the sream and waterfalls.
