Check oxygen levels in your ponds to prevent koi loss

[Charly]

Please check your pond's oxygen levels if you're unsure. I was called to an emergency in Epsom where the oxygen was at 2.0 mg/L, that is way too low. The owner lost three Koi. After fixing blocked venturi and skimmer feed, the Koi became more active within half an hour, a simple oxygen kit could save your fish, especially in hot, stormy weather.

I experienced a similar fright one time. Low oxygen levels almost took out my koi. I cleaned the venturi, increased the aeration, and the fish recovered quickly. Those test kits are an affordable way to ensure everything's okay

Yeah those simple tests can really save the day, it's crazy how fast oxygen levels drop and how quickly fish respond once you fix the aeration

Right, and it was amazing to see the fish perk up within minutes! What about you, are you using diffusers or stones in your setup?

I'm new to fishkeeping so I have to ask, how do you check oxygen levels in a pond? Is there a simple way to keep oxygen levels steady, or do you have to adjust things all the time?

Yeah, I agree those sudden drops can be brutal on fishes! I say get an inexpensive dissolved oxygen meter and consider adding an air pump for extra peace of mind during heatwaves.

Great question! I use a handheld dissolved oxygen meter, it is easy to read and accurate, to keep levels steady, ensure good aeration with venturis, air stones, or surface movement, especially during warm weather

Yup, heatwaves can hit hard, do you run your air pump 24/7 or just during peak temps? I've found constant aeration really helps keep things stable during those sudden weather shifts
