DIY Pond Filtration

I'm showing you how I built a duck pond filtration system to upgrade my old pump that just wasn't doing a good job. Here's the stuff I bought from Amazon in the video: VIVOHOME Submersible Pond Pump (530 GPH) - I didn't have great luck with this one. https://amzn.to/4bhUX6i Pond Pump (3900GPH) - This is the one that works! https://amzn.to/4aUBnx4 1-1/2 PVC NPT bulkhead fitting - This is the fitting in the middle of the tote. https://amzn.to/4bgLJqQ IBC Tote Fittings Adapter 2" Female Buttress Coarse Thread x 2" Male NPT Pipe - This is the adapter at the bottom of the tote. https://amzn.to/3WkAtFv The pipe the leads back to the pond is 2" PVC pipe and the pipe at the bottom of the tote underneath all of the lava rock is 1-1/2" PVC pipe. I just bought the pipe and the fittings at Lowe's.
