Frequently Asked Questions

What koi grades does Tropical Lagoon Aquarium typically carry?
Stock varies, but local fish stores in this category generally carry a range from pond-grade koi, which are great for beginners, to higher-grade ornamental fish for more serious hobbyists. It's best to call ahead if you're looking for something specific, since inventory changes frequently.
Can I bring in a water sample to get it tested?
Many local fish stores welcome water samples and can test for key parameters like ammonia, nitrite, nitrate, and pH. Getting your water checked before adding new koi is a smart move and can prevent a lot of problems down the line.
How do I acclimate new koi to my pond after buying them?
The standard approach is to float the sealed bag in your pond for 15 to 20 minutes so the water temperatures equalize, then slowly introduce pond water into the bag before releasing the fish. Staff at the store can give you specific guidance based on the size of your pond and the time of year.
Is Silver Spring a good area for outdoor koi ponds?
Yes, Montgomery County's climate supports year-round outdoor ponds, though you'll need to manage them differently through winter. Most Maryland pond owners keep their pumps running through the cold months to maintain oxygen levels and stop ice from fully sealing the pond surface.
What should I feed my koi during summer in Maryland?
During the warmer months, koi are active and their metabolism is high, so a high-protein food works well for promoting growth. As temperatures drop in fall, you'll want to switch to a wheat germ-based food that's easier for koi to digest when their systems slow down.
How many koi can I keep in my pond?
A general rule is 10 gallons of water per inch of fish, but filtration quality plays a huge role in how many fish a pond can realistically support. The staff at a local fish store can help you calculate a safe stocking level based on your specific setup.
