Another cloudy water puzzle

Postby Dana C » Mon Jan 21, 2013 5:58 pm

A couple of months ago, I changed at least 50% of the water in my 55 weekly and sometimes up to 80%.
A few weeks ago it has gotten much colder with lows in the single digits and highs seldom over 20.
The earlier water changes were clear for the most part and sometimes a bit cloudy, (white).
Now if I change even 2 gallons with treated tap water at the correct temp., the tank gets cloudy for a few hours.
Also, white stringy stuff appears to be clinging to the rocks in the tank which dissapears along with the cloudy appearance of the water.
My Oscar sort of sulks when the water is changed in the morning but is fine late in the afternoon.
My temp is 75, ammonia is 0, nitrites 0, and nitrates around 30-40.
Does anyone have any idea about this? The water here in Southern Idaho is extremely hard and I am wondering if the cloudy water has something to do
with the cold. The water company told me that they are not doing anything different.
Any ideas.

What you are witnessing is likely a combination of effects resulting from colder water. Colder water holds more dissolved gases and this effect increases when the water is under pressure (as it would be in your pipes). Once released from pressure these gases will start to dissipate and in the process, interact with the minerals in your water (calcium, manganese, magnesium, etc...) resulting in the temporary cloudiness you are describing.

Thanks. I thought it was related to the cold. While I make sure the water going into the tank is close to the tank temperature, it makes sense that the TDS in the tap water would be high as the temperature coming straight out of the faucet is around 50.
Like I said the Oscar doesn't seem really stressed about it and my chemistry is ok except for the struggle to keep the PH below 8.2.
He or she is a bit of a drama queen and any little change causes a sulk.
Thanks again,
Dana

My bad, I meant gases, not solids.
