Frequently Asked Questions About Water Garden Spring Start-up

When should I add beneficial bacteria to my pond in spring?

Start adding beneficial bacteria once your pond reaches the recommended water temperature for the product you're using. Always check the product label, as temperature requirements can vary between formulas. The Pond Guy Seasonal Defense is designed for use during cooler spring conditions when water temperatures are between 40–50°F, helping support your pond as it transitions into the new season.

Should I clean my koi pond before starting it up for spring?

Yes, spring is a great time to remove leaves, sludge, and other organic debris that collected during winter. You do not necessarily need to completely drain your pond. Focus on removing excess debris, getting your filtration and circulation running properly, and preparing the pond for the warmer season ahead.

When should I start feeding my koi again in spring?

Wait until the pond water is consistently around 40°F or warmer before feeding your koi. Start with an easily digestible spring and fall fish food formulated for cooler water. As temperatures consistently rise above 50°F, you can transition your fish to their regular warm-season diet.
