OASE BioSmart 5000 Pond Filter

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.

The media could not be loaded. Hands down the simplest and the best filter I've ever had!!!........I went through countless pond filters all pressurized uv power-operated each and every one had a leak each and everyone eventually had a power shortage and each was three times the price not to mention how difficult it was to clean it. In The five years I've had my pond I've never had a filter that made the water crystal clear until I purchase the oase biosmart 5000, in a matter of hours the water was crystal clear clear than the day I filled up the pond for the first time my pond is roughly 2000 gallons Plenty of Fish at about 2 feet deep I can't believe how clear it is right now I can see the way to the bottom the fish seems happier the plants look healthier all in all a wonderful purchase highly recommended super easy to install I don't get the people to write the installation is difficult, all you have to find is a 3in rubber sleeve to adopt into the outlet took me exactly 1 minutes to figure it out people need to learn how to improvise and you got to do the same thing for the second inlets and attach rate post shut off so when they're water rises it won't drain out from the back, literally altogether five minutes of installation.Cleaning is so easy one minute to squeeze the sponges rinsing inside where the hose connection is and put the lid back on couldn't ask for a better more efficient filter. Those of you who have really murky water to begin with you might have to clean the filter on a daily basis in the beginning until the water condition adapts and then all you have to do is maintain it maybe once a week depending on how much sun exposure you have and algea buildup. I hear some reviews about people who complain about maintenance, you're pond owners there's no such thing as Carefree or maintenance-free ponds it always requires some cleaning no matter what.To do it to minutes a week won't hurt anyone.
