The BioSmart is a flow-through filter that is both innovative and efficient. It undertakes biological and mechanical filtration and offers maximum oxygenation. With a sludge drain that allows for easy removal of coarse debris, the BioSmart is built for work - there is no need to remove or manually unclog the filter foams. Distinct filter zones promote the settlement of beneficial bacteria responsible for different phases of the nitrogen cycle, increasing the conversion of harmful ammonia in the pond. The BioSmart is Nature-friendly technology with positive results for local wildlife and fish stock. With a built-in cleaning indicator and water temperature display, the unit requires minimal maintenance. The BioSmart UVC 1600 with included UV Filtration is for ponds up to 1,600 gallons; the BioSmart 5000/10000 for up to 10,000 gallons. For maximum effect it can be combined with the Vitronic 18 - 36 Watt UV Clarifiers. When used in conjunction with the BioSmart filter, the AquaMax Eco Classic 1200-2700 or AquaMax Eco Premium 2000-3000 and the Vitronic UV Clarifier qualify for the OASE Water Guarantee.

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.

I have a Koi pond approximately 8000 gallons and 17 fish medium to large in size. They’ve been in the Pond for 12 years. I have a bead filtration system with a UV light on it, that was doing a pretty good job, but I was still having cloudy water, sometimes greenish hue. I used to try different chemicals and products to clear up the water. none of that stuff ever seem to work. After reading many reviews on YouTube, I came to the conclusion that the best way to keep your water clean is to add extra filtration so I bought this pump and filter, and has done a fantastic job of finishing off what the bead filter was not accomplishing the two pieces together worked very well. The only stuff I put in the water now is the good bacteria, I put 2 gallons in in the spring and maybe add one more in July and one more in September. But that’s it no other chemicals the fish are very healthy. I’m thinking about adding another one of these just to really keep the pond clean. But for the price, I’m very happy with it. It was easy to set up and it’s easy to clean. You still need to clean out your pawn at a minimum every two years, it doesn’t matter what filter you have you will always need to clean out the pond to get all the sediment out of the bottom. But this thing works really well, I imagine if you had a smaller pond 3 to 4000 gallons it may be all you need.

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.
