Indoor Eagle Habitat Pond: Algae, CO₂, Test Kits

Artificial indoor pond in eagle habitat. Tap water vs. pond water samples in cups—no change in 10 days. Asks: test kit recommendation, phosphate remover timing, volume measurement.

CO₂ Is Likely Culprit

No algae growth in cups = tap water not the source. CO₂ doesn't transfer to cup samples. High CO₂ fuels algae. Test pH + KH → use CO₂/pH/KH chart.

Test Kit Recommendations

• API Freshwater Master Kit (pH, ammonia, nitrite, nitrate) + API Phosphate + API KH (alkalinity).
• Available at pet stores, Walmart, or online (thatpetplace.com, Amazon).

Phosphate Remover

Add to clean, refilled pond—prevention > cure. But first, measure volume:

• Rectangular: L × W × Avg Depth × 7.48 = gallons
• Irregular: Time fill with known flow rate (gpm × minutes).
• Salt dilution: Add known salt, measure salinity rise → calculate volume.

Fix CO₂ with larger pump/surface agitation. Test, then target nutrients.
