While I was working in the garden last week, I decided to do some cleanup work around the yard and start getting the pond ready for winter.
Sometimes winterizing includes a water change. Sometimes it involves skimming out fallen leaves. But it always involves removing floating plants and bringing a few inside before they freeze. Too many times, I’ve neglected to do that in a timely fashion, and I’ve found myself scooping slimy, dead, decaying water hyacinths and sludgy remnants of what used to be water lettuce out of the pond in the spring because fall turned to winter faster than I expected, and I didn’t get the plants out before they froze.
Not this year. Last weekend, I used a pitchfork to scoop most of the plants out of the pond, leaving just a few lonely specimens floating on the surface to provide cover for the goldfish until it gets cold enough for them to go dormant.
When I removed the plants, I was delighted to discover all six of the feeder goldfish I’d dumped out there this summer were alive and well.
I moved a few plants into a bucket of water and stuck it in a sunny corner just outside a south-facing window, where it should stay above freezing all winter.
Hedging my bets, I also half-filled a miniature washtub with water, threw a hyacinth, a clump of water lettuce, and a few stray bits of duckweed in there, and parked it in the living-room window, where it should make a nice centerpiece for the next few months.
With nothing but fish and algae to muck up the water, the pond doesn’t really need the elaborate, multi-stage filtration system I designed for it last spring, so I disassembled the whole setup and replaced it with a variant on the biofilter I had on my pond in Cape. I upgraded the original design by placing the pump inside a half-gallon sherbet tub with 3/8-inch holes drilled in it, wedging chunks of old memory foam around it, and setting the whole thing inside a one-gallon ice-cream tub with 1/4-inch holes drilled in it. I slipped a layer of Scotch-Brite pads between the tubs, providing additional filtration, and anchored the lid with a bungee cord.
After I put away the excess filter components, I was left with a stack of cinderblocks just right for another project I’d been considering for several months. I’ll show you that one tomorrow.
