❓ Frequently Asked Questions

How big should a garden pond be?+

Minimum recommended: 4×6 ft, 250+ gallons for a planted water garden. For goldfish: 500+ gallons (100 gallons per fish). For koi: 1,000+ gallons minimum (250 gallons per koi). Depth: 18–24" minimum (24–36" for koi, 3 ft+ in freezing climates). Bigger is always easier to maintain — larger water volume is more stable. Most popular residential size: 6×8 ft, 500–800 gallons.

How do I keep pond water clear?+

Clear water formula: adequate filtration (biofilter + mechanical), 50–70% surface coverage with plants (lily pads shade out algae), proper fish stocking (don't overstock), beneficial bacteria supplements monthly, UV clarifier for persistent green water, and avoid overfeeding fish. Most clear water issues are caused by: too many fish, too few plants, direct sun without shade, or inadequate filtration.

Do garden ponds attract mosquitoes?+

Not if managed properly. Moving water (fountain, waterfall, stream) prevents mosquito breeding — they need still water. Fish eat mosquito larvae voraciously — even 3–5 goldfish eliminate larvae. Mosquito dunks (BTI) are biological and safe for fish, plants, and wildlife. A properly maintained pond with fish and water movement actually REDUCES mosquitoes by providing predators.

What do I do with my pond in winter?+

In zones 3–6: Stop feeding fish when water drops below 50°F. Run a de-icer or floating heater to maintain a small opening in ice (gas exchange). Remove pump from waterfall and store, but keep a small circulation pump running. Remove tropical plants before first frost. Hardy water lilies survive frozen at the bottom. Never break ice by hitting — shockwaves can kill fish.

How much does a garden pond cost?+

Container pond: $50–$300 DIY. Small liner pond (4×6 ft): $200–$500 DIY. Medium pond with waterfall (6×10 ft): $500–$2,000 DIY. Professional installation of medium pond: $3,000–$8,000. Koi pond: $5,000–$15,000. Natural swimming pond: $20,000–$80,000. Ongoing costs: electricity for pump $5–$20/month, fish food $10–$30/month, supplies $100–$300/year.

Can I build a pond without a pump?+

Yes — a 'natural balance' pond works without a pump IF you have: enough plants (70%+ surface coverage), no more than 1 small fish per 10 gallons, natural beneficial bacteria, and accept some algae. No pump means no waterfall or fountain sound. Water will be still. Add mosquito fish (Gambusia) for mosquito control. Wildlife ponds often work best pumpless. Expect green water initially — it clears in 6–12 weeks as biology establishes.
