Yesterday (Tuesday, 7 April 2026) was a big day for the pond. After noticing the water level falling, I purchased a Boogie Blue Plus Garden House Filter (that’s an Amazon Affiliate link; I receive a portion of any purchases made through this link, at no additional cost to you) and topped off the pond.
I also had a shipment of Japanese Trapdoor Snails from www.prettykoifish.com. I have been dying to add these massive mollusk beauties to our pond since I first learned about them. They are the cleaning crew of any pond, and as they settle in and become active, they’ll deep clean the water and the liner.
Right now, our pond water is very murky. That’s actually good for the koi—they prefer it to be murky—and is a sign of healthy biodiversity. The only downside is that we can’t see our fish unless they’re coming up to feed! It will take a few weeks, maybe months, but the Japanese Trapdoor Snails should start to hoover up lots of detritus.
