Regular Member Sharkbait3 Posted May 31, 2012 Regular Member Share Posted May 31, 2012 Hi...this is Mr. Sharkbait here. At our old place, the Ph from the tap was 7.6 and quickly raised to 8.4 once in the tank and the carbon dioxide in the water out-gassed. Ph swings of this nature do not pose a risk to fish. But Ph shifts do to changes in TDS (total desolved substances) do pose a risk to fish.....it is the dissolved minerals (calcium, iron, magnesium and the like) that can cause a fish to have problems regulating how much water passes through its skin. The best way to tell what is going on with your Ph is to do a Bucket Test. Test water straight from the tap for Ph, Kh and Gh. Fill a bucket with water, aerate it for 24 hours, and test for Ph, Kh and Gh. If only the Ph has changed between the Tap Water and Bucket Water, then your Ph swings are due to out-gassing of carbon dioxide or other acidic gasses (will show as an increase in Ph) or of oxygen and other alcaline gasses (will show as a drop in Ph) and do not pose a risk to your fish. If the Kh or Gh is significantly different between the Tap and Bucket...then you may face serious risk to your fishes. Tim 0 Quote Link to comment Share on other sites More sharing options...

I have done the kg and gh test and it is the same between my tap and the tank (which has plenty of aeration) - both taking the exact same amount of drops. And it only takes 4 hours for my tap ph to match my tank. Are you saying that i won't have to age my water for water changes? I can do the test again just to be sure, but so far no one else has mentioned anything like you have although i find it very interesting. Did you also have a hard time getting your tank to cycle? Mine has been a true pita so far, very stubborn. I appreciate your information and am curious to see what others have to say about it. 0 Quote Link to comment Share on other sites More sharing options...
Regular Member GoldfishGraycee Posted May 31, 2012 Author Regular Member Share Posted May 31, 2012 Lets do a 30% water change then add full ammonia hun Water has been changed and ammonia added. *fingers crossed*! 0 Quote Link to comment Share on other sites More sharing options...
