Oase BioSmart 1600 Pond Filter

Two weeks ago we could not see our koi in the water it was pure mud, all 8000 gallons of it. Everything they claimed about this product is correct and better, super easy to install and works fantastic! We purchased the 10000 gallon filter for our 8000 + gallon pond. We have 12 Koi, some very large We could not see our fish at all. Removal of an orchard directly behind our house and construction of a new housing project for two years now, high winds has filled our pond with dirt and muck 6 -12 inches + deep. Water quality was very poor no matter how much we changed water or vacuumed we could not get all the dirt and muck out of our pond. Three years ago we spent $7000 emptying cleaning and adding new pumps, lights, fountain etc. so we could have a clean and healthy pond for enjoyment. But now We have spent $1000's on bacteria and chemicals, eco-safe and not so eco-safe to clean it. Koi got ulcers even though we have a very expensive bead uv filter system with two pumps, it was here when we bought the house 10 years ago. It could not do the job. I ordered this OASE BioSmart filter without telling my husband because it was the last resort to try to save our koi and be able to enjoy the beautiful backyard, he was ready to give the koi away and fill in the pond, which would have been 1000's of dollars also (google it, very expensive for a huge pond). The pond has two waterfalls and two creek beds, they also full of muck and dirty water. I only wish I would have taken a picture of before our OASE BioSmart filter. Our pond is now clearing, muck is disappearing, and the pump has only been up and running for a little over 2 weeks. We noticed it clearing in only one day and everyday since it is better. As you can see in the pics we have some more to go before crystal clear but now We are enjoying our koi and they are loving it and starting to spawn as soon as the water started cleaning up. Thank you, thank you and thank you for saving our koi and cleaning up our pond. PS: We did not add the UV unit but may do so down the road. A happy life now!

Did the job and solved the filtration problem I was having

Excelente sistema de filtración, fácil de instalar y el uso

JUST bought and installed June 2020, BUT! It has worked VERY WELL so far! Our pond went from looking like a MUD HOLE to being so clear I can see the bottom! In just a matter of days. The fish are much more active and happy; there are now a ton of frogs/toads and snakes...a very thriving pond, thanks to the filter. It seems very well made. I've already done a thorough clean and backwash (and used the backwash to feed/water surrounding plants, trees, shrubs...they love it). I did the cleaning before it was indicated, just to see what it was like. It is easy to install, easy to maintain...perfect for elderly pond owners or those not wanting much filter maintenance. Hints/tip: drain/backwash prior to trying to lift the sponge filters out. I tried before draining and they are extremely heavy...and our filter is elevated. Also, I added beneficial bacteria and some hornwort plants. Already had lilies and hyacinths in the pond I will update again end of summer and next year if this product fails or doesn't perform as well but in all honesty, it seems like a MONEY WELL SPENT! Great value and a healthy, crystal clear pond in no time! Highly recommend (NOTE: local pond retailer has several of these filters and swears by them; and has had their filters for YEARS, FYI...so the product likely lasts).

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.
