I researched that extensively a few yrs ago as our water is stored 200 ft underground in a well. It's the hot/warm water that has a ton more CO2. The cold water has a lot less. The problem is in the winter people turn the hot water faucet partway on to warm the water up-that's where the CO2 problem comes more into play because heated water has more CO2 coming up through the pipes & through the hot water heater from being stored underground. The cold water here (Oklahoma) has to come clear up from 200 ft under the ground and it's COLD, about 55 degrees.bigspizz;3276928; said:Yes, that is normal...The benefit for us is that when it is warmer, there are WAY less dissolved gasses in the water. You can change huge amounts during this time safely, as gas embolism (which is a threat, in the cold water, high gas months, of Winter)kills more fish, than common hobbyist know![]()
