If there is one job that sets up your whole pond season, it is the spring opening. I have watched it go both ways plenty of times. Do it right and the water clears fast, the fish come through healthy, and you dodge that nasty spring green-water surge. Do it wrong, or wait too long, and you are playing catch-up until fall. Here is how I think about it.
Watch the Water, Not the Calendar
Everyone wants a date. The pond does not care about dates, it cares about temperature. I like to start once the water is holding steady around 50 degrees. Around here in Southeastern PA that is usually sometime in March or early April. Open around then and you get ahead of the algae, while your fish are still sluggish and easy to work around.
The Order I Work In
- Clear the surface first. Pull the winter netting, skim the leaves, get out whatever collected over the cold months.
- Wake up the equipment. Reconnect and fire up the pump, clean the filters, and look everything over for winter damage, the lines, the waterfall, the liner edges.
- Test before you trust it. Check the water before you put the fish back on a normal routine, and treat whatever needs treating.
- Ease the fish in. As things warm up, start light with a food made for cool water. Do not jump straight to summer feeding.
A Few Things I Always Tell People
- Do not overfeed early. Cold fish barely digest, and the extra food just turns into algae fuel.
- A little cloudiness for a bit is normal while everything rebalances. Green that sticks around is not.
- If your pond got neglected over the winter, or you just bought a house with one you have never touched, do a one-time deep cleanout first. It makes everything after it easier.
