Just set it up and seems to work great for our 1800gph display tanks!

Good both quality and cost. Keep my pond low maintenance and clear. I'm not used to write feedback but this one serve me well so it deserves a good review.

For some reason right after our yearly cleanout, we developed an algae problem. I went at first with a pressure filter with UV. While it works great I found myself having to clean it twice a week. Did a lot of research and decided a mid pond pump with a drum filter was the way to go. We have an older Aquascape style pond with a skimmer and a waterfall but for some reason this year it just wasn't enough. Our pond is only 1435 gals. I didn't need a huge drum filter just something to help the skimmer out. I coupled this with a half off ponds 2100GPH pump but at first used too small of a tubing. I purchased 1 1/2" pond tubing to mate the pump to the filter and it's now working great. Took a load off the waterfall filter also. It's all automatic. I check it every couple of days but no maintenance required so far. Just remember to match your pump and tubing to the size recommended for the filter, It's amazing for the price point! Edit: It's been14 months and the power supply has died. I contacted Elelife but no response so far. It has worked great with minimal maintenance to this point but lack of repair parts should be a concern. I lowered to 3 stars due to lack of replacement parts.

What's bad: 1. Box was delivered crushed. The cardboard isn't nearly strong enough for shipping these filters. The filter seems to function ok though, miraculously.. 2. Filter is rated at 4000 gph, but I couldn't even get close to that. With my pond water about 3000gph was the best I could do, without the filter in a perpetual cleaning cycle. No idea where the 4000 came from. 3. This filter is pressure input, gravity output. You need to match the filter output fitting, so free flow output matches pressure input. Most importantly, the water output can never rise above the top of the output fitting. That means this filter must be physically above all output destination fittings in order to function correctly. 4. Input water quality greatly affects this filters performance. Leaves and twigs cause bad things to happen when they get inside the drum. Need to filter those out first. The cleaning cycles are supposed to wash the waste out the sewage port. But about 5 % of that waste, ends up splattered on the inside walls of the filter . This ends up right in the output water. So in my case, I still have to clean this filter monthly. This was not designed to be easy to clean!. 5. 200 line screen is equivalent to a 74 micron filter. This works wonders for clearing the pond water of flotsam. But fish slime passes right through. So you end up with fish goop all over the inside of the filter, which then gives rise to worms, bacteria, which all happily move into the filter. It's really got to be cleaned regularly to function correctly. 6. This is NOT fully automatic, set and forget. Did I mention you have to clean it too?!, and yes, it was not designed to be easy to clean. It's a pita in fact 7. You have to adjust the flow rates in and out to minimize washing cycles. For my setup, the washing cycles waste about 35 gallons of water each day. This means your plumbing needs to support flow rate limiting, and you'll need to have a way to constantly replenish the water for your fish as it's lost due to filter cleaning. 8. Maybe other brands would be easier to deal with, but this is the only one I've ever bought, so I have nothing to compare too. It works. 9. Comes with no warranty, zero, nothing. Cross your fingers. The good: 1. It actually works to clear the pond water. 2. The cleaning cycle is a pleasure to behold! 3. This thing dropped my labor from cleaning my filter sponges every 2 days, to cleaning a drum every 3 to 4 weeks. Saves me a lot of time. But it's not cheap, and it's not easy! 4. You get about 35 gallons of free fish fertilizer every day, so pair this with a big garden, and watch your plants grow! By the way, fish fertilizer stinks, so prepare yourself!
