Its automatic backwash cycle efficiently removes debris while enabling waste recycling as organic fertilizer, making it an eco-conscious choice for professional pond and aquarium management. ## Description Automatic back-washing mode:When the pump the water from the fish pond to the inlet bin of the micro-filter and flows into the drum, the drum filter net accumulates foreign matter to a certain amount to block, resulting in reduced water output, the inlet bin water level rises, the liquid level sensing switch automatically opens, concurrently,the controller opens the back-washing mode。1： Put the water pump into the fish pond，connect the outlet pipe with the micro-filter inlet pipe 2: The water outlet is a natural outflow to the fish pond, the pipe diameter can not be less than the factory configuration, otherwise the micro-water level is too high, the machine starts continuously 3: The sewage pipe can be connected to the sewer or stored for use as fertilizer 4: After the pipe is connected, plug in the controller power supply,When the device is delivered, the controller has been adjusted to automatic mode by default. .diameter Specification ：Inlet diameter 2-1/2"(73mm)outlet diameter 4"(114.3mm)Sewage diameter1-1/2(48.25mm)Product size：35“*23”*23“ All metal components are made of 304 stainless steel. Review: Ok, A real review, not a Bot! I ordered 2 of the 8000 GPH "rate" ones with UV sterilizer. Got my first one, BUSTED and smashed.... my other one MIA. I returned the one I got because it was beyond fixing. Reordered and after some time got 2 that were better packed. I set them up without issue and the results are EXCELLENT!!! I use one on a Dwarf Caiman Pond (Crocodilians) and another on Large Alligator Snapping ponds. I use the drum filters to remove a fair bit of debris etc and also have Biological filtration included. I love how much material is caught by the drum and I backwash the drum screen back into the system but use a filter sock to separate the debris. This works well as there is no water loss and I can just change out my sock and save myself a fair bit of the hassle of clogging my Bio filters. Overall, I really like the products and have had for about 8 months and will buy more for other various needs. Worth the money in my eyes and I have a huge amount of experience with filtration, fish and animal management. I know when things suck and this is actually quite decent considering the price etc..

Review: Just set it up and seems to work great for our 1800gph display tanks! ## Features - Strongly recommend installing an automatic water replenishment valve: a fully automatic water level controller that automatically stops when the water is full,because you'll need to have a way to constantly replenish the water for your pool as it's lost due to filter cleaning.If you are willing, you can prepare a frame with filter cotton for secondary recycling,or you get about 10-30 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! - Can be used for Filter large fish ponds, with an hourly water output of 8000 gallons, basically meeting the current Filter needs of all fish ponds.General recommendation: The hourly flow rate of the microfilter should be close to the volume of the water, that is, the water should be purified once per hour.best match:elelife 12000GPH-100W,High Flow Submersible Water Pump Water Fountain Pump - Aquarium Pump - The cleaning cycles are supposed to wash the waste out the sewage port. But about 2 % of that waste, ends up splattered on the inside walls of the filter . The drum filter is dried for a long time or the particles are solidified in the filter for a long time.which will also cause the equipment to work frequently, and can be cleaned drum and walls with water cannon or soft toothbrush.This was designed to be easy to clean!. - When the drum is rotating, do not press the drum by hand, otherwise the motor gear will be damaged .do not start the equipment before water, otherwise the cleaning pump dry burn damage. The cleaning nozzle tube can be manually rotated to suitable Angle. lf the cleaning nozzle is blocked, the stainless steel nozzle needs to be twisted out for cleaning. - The chassis shell is made of durable and PP board, All metal components are made of 304 stainless steel。which is acid and alkali resistant. Over 10 years of service life in outdoor exposure to sunlightThe built-in filter adopts a rolling structure and can filter the water in the swimming pool 360 ° without dead angles. Keep your Aquarium or pool clean Automatic cleaning automatic discharge，Efficient filtration of fish manure particles and impurities，Efficient bacterial cultivation and stable water quality，No need to clean the filter material, bid farewell to troubles。 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5CLDRJ2 | | Batteries Included | No | | Best Sellers Rank | #56,168 in Pet Supplies ( See Top 100 in Pet Supplies ) #3,183 in Aquarium Accessories | | Color | GREY | | Customer Reviews | 4.2 4.2 out of 5 stars (32) | | Date First Available | 4 June 2024 | | Item Weight | 15.5 Kilograms | | Item model number | ELE-US-0029 | | Pet Life Stage | All Life Stages | | Product Dimensions | 73.66 x 48.26 x 48.26 cm; 15.47 kg | | Quantity | 1 | | Specific Uses | Filter for Aquariums | | Wattage | 100 watts | | batteries required | No | ## Images ![Rotary Drum Filter,Canister Filter,RDF Fully Automatic Water Self-Cleaning Filtration for Koi Pond,Fish Pond,Aquarium,Seedling Cultivation Base,Aquaculture,Hydroponics (4000GPH Standard Edition) - Image 1](https://m.media-amazon.com/images/I/71XZ5Qj+pCL.jpg) ## Available Options This product comes in different **Model** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by Z***S on 6 May 2025* Ok, A real review, not a Bot!
