Texas Pond Summer Crisis: Heat, pH, Algae & Feeding Protocol

3,000-gal TX pond, 92°F → cooled to 85°F, bubbles, brown algae, fish lethargic, algae eaters dying. Heat + high pH = toxic combo.

Immediate Actions

1. Stop feeding at 90°F: Fish can't digest. At 80–85°F: spring/fall formula only.
2. Test pH: High pH + heat = ammonia toxicity. Target 7.0–7.5.
3. Add bacteria + salt: Reduces waste, relieves stress.
4. Shade NOW: Shade cloth, floating plants, dye.
5. Aeration 24/7: Air pump + diffuser at bottom.

Algae Eater Deaths

• Plecos, SAEs = tropical. Die at 85°F+. Not for TX ponds.
• Koi/goldfish tolerate heat better — but stressed.

Long-Term TX Strategy

• Palms/bananas/elephant ears = shade (plant NOW).
• Deeper pond (4+ ft) = thermal refuge.
• Chiller or groundwater exchange for valuable fish.

92°F kills. 85°F survives with shade, aeration, no feeding, pH control. Algae eaters are the wrong species.
