Aquascape Eco: Frequently Asked Questions


How many fish can I have in my pond?

Great question! The number of fish depends on your pond’s age and size.

  • New ponds: Start with one inch of fish per square foot of pond surface.

  • Established ponds: You can go up to two to three inches of fish per square foot.
    Remember to dechlorinate new ponds before adding fish!

How do I introduce new fish into my pond?

To make your fish feel at home, follow these steps:

  1. Check the pH – It should be between 7.0 and 8.0.

  2. Dechlorinate the water – Use a product like Tetra’s Aquasafe.

  3. Equalize the temperature – Float the sealed fish bag in your pond for 15 minutes in the shade.

  4. Gradually mix water – Every 5 minutes, remove a cup of bag water and replace it with pond water (repeat 3 times).

  5. Release the fish – Avoid pouring bag water into the pond.

  6. Salt dip (optional) – If unsure about fish health, dip them for 15 seconds in a 1 lb salt per gallon solution (no iodized salt!).

How much should I feed my fish?

Feed only what they can eat in 5 minutes.

  • Summer: High-protein food.

  • Spring/Fall: Wheatgerm or low-protein food (easier to digest).

How do I know if my fish are stressed or sick?

Watch for these signs:

  • Not eating

  • Gasping at the surface

  • Fins clamped close to body

  • Hiding or isolating

  • Rapid gill movement

  • Flashing (rubbing against surfaces)

  • White patches or fin damage

What should I check if my fish are dying?

Test for:

  • Chlorine levels (make sure water is dechlorinated!)

  • pH, ammonia, nitrite, and oxygen levels

  • Potential toxins (like runoff from nearby chemicals)

  • Electrical hazards (yes, it can happen!)

How can I protect my fish from Blue Herons?

  • Pond netting – The most effective method!

  • Blue Heron decoy – Move it every few days (they’re territorial).

  • Fishing line perimeter – String it 2-3 feet above ground.

  • Get a dog – Some pups love chasing them away!

Why use pond salt?

Adding 1-1/4 cups per 100 gallons helps fish by:

  • Reducing stress

  • Improving gill function

  • Adding essential electrolytes

For ponds without plants, you can use 2-1/2 cups per 100 gallons.

How can I control algae?

Try these natural and mechanical methods:

  • Oxygenating plants – They compete with algae for nutrients.

  • Floating plants – Cover 60-65% of the surface.

  • Biological filters – Matala BioSteps or similar.

  • Pumps – Run them 24/7 (bacteria die if shut off too long).

  • UV clarifiers – Optional but effective!

What about string algae (blanket weed)?

  • Manually remove it.

  • Use an algae control product like PondCare AlgaeFix.

How do I calculate my pond’s surface area?

  • Rectangular pond: Length × Width = Square feet

  • Circular pond: (Half the diameter)² × 3.14 = Square feet

How do I calculate my pond’s water volume?

  • Rectangular pond: Length × Width × Depth × 7.5 = Gallons

  • Circular pond: (Half the diameter)² × 3.14 × Depth × 7.5 = Gallons

How can I estimate my pond pump’s electricity cost?

Use this formula:
(Amps × Volts) ÷ 1000 × Cost per kWh × 24 × 30 = Monthly cost
(Your power company can tell you your kWh cost.)

How can I control mosquitoes?

  • Fish will eat the larvae!

  • No fish? Use Mosquito Dunks (BTI bacteria), one per 100 sq. ft.

What’s special about hardy water lilies?

  • Perennial & frost-tolerant

  • Bloom for 3-5 days, opening in the morning & closing at dusk.

  • Low maintenance – Just give them 5-6 hours of sun and fertilize every 2-4 weeks (May-Sept).

  • Colors: Pink, red, white, yellow, peach/orange.

What about tropical water lilies?

  • More exotic & fragrant

  • Frost-tender (treat as annuals in cold areas)

  • Hold blooms high above water

  • Vibrant colors: Blue, lavender, pink, purple, red, yellow, white

  • Two types: Day bloomers & night bloomers

  • Needs warm water (70°F+)

What makes lotus plants unique?

  • Huge, dramatic flowers & floating leaves

  • Bloom all summer into fall

  • Requires 5-6 hours of sun

  • Plant in large containers & fertilize regularly

What about marginal (bog) plants?

  • Thrive in shallow water at pond edges

  • Provide height & texture to your water garden

  • Many bloom with pink, white, or yellow flowers

What are floating plants good for?

  • Add shade & color to ponds

  • Reduce algae by blocking sunlight

  • Provide fish spawning areas

Why are oxygenating plants important?

  • They remove impurities & prevent algae

  • Absorb carbon dioxide & release oxygen

  • Provide shelter for baby fish

How do I winterize water lilies?

  • Hardy lilies: Move to deepest part of the pond.

  • Tropical lilies: Store indoors in a heated aquarium or moist sand (50-65°F).
