OaseBioSmart 1600 Pond Filter

My Pond is about 6000 Imperial Gallons I had this filter running all last Summer Using the OASE 1900 GPH Pump. It was at the Low end of the pond, so as to harness as much as possible. I have about 75-100 Fish all just gold fish a few multi coloured ones one big Butterfly Koi about 20+" all healthy. This filter removed, over the summer about60 to 80 pounds of fish waste and general dust leaves etc Its a bit of a bitch to clean but it keeps you out of trouble. Yes its worth the price. Yes I would buy it again. A Snap to install!

Excelente sistema de filtración, fácil de instalar y el uso

We were on the point of giving up. Our pond water was totally green every summer, and we could only see the fish when they were within the top foot or two of water. We tried different filters, barley, and algicides. Nothing worked.Our pond is 8'X10', with half of it 2 feet deep, and half 4 feet deep, so there's a lot of water in it. Previously we had an Aquaviolet filter, but it just didn't do the job.We were going to give our fish away and fill in the pond. Purchase of this filter was a last attempt. The results have been amazing. The water is crystal clear, and we can see right to the bottom of the pond. We used to have to pull the pump out every second day to wash the algae off the mesh bag protecting it, and we changed the pond water every second week. UV lights, different filters, nothing seemed to work. That's all changed now.It was difficult to pipe in. I used 1.5 inch plastic hose with spiral re-enforcing. It has nearly impossible to find connectors for it. I had to purchase things for toilets and use steel hose clamps. I used a splitter to get the full volume of water pumped up to the two inlets on top of the filter.My initial impressions were that it looked flimsy and I was disappointed to see that the filter media was only a few sponges. That all changed as we began to see how effective it is.Clean out of it is really easy and quick. I just shift the filter a bit so that they clean-out port is over the edge and let it drain.With the larger diameter piping that it's designed for, we can run much more volume through it than anything we have had previously.The water is so clean now that we only need to even clean the mesh bag over the pump about once a week. I only changed the water once during this whole season. The sponge filters only need to be squeezed about every couple of weeks.I highly recommned this product.

BUYER BEWARE: the outlets for dirty discharge and back to pond are metric sizes. DM70 relates to 2&3/4 inches. no adapters available but same unit sold in US has 3" Imperial outlets. For the price of this great filter you would think they could at least supply a proper adapter. Had to use glue, gorilla tape and hose clamps. A short term fix at best.Apart from above unit works great. Couldn't see my fish before but next day almost completely clear. Hard to believe after the state the pond was in before.

Did the job and solved the filtration problem I was having
