Pbalz Posted February 2, 2021 Share Posted February 2, 2021 What causes your parameters to move my calcium was up 110 from last week my all up 1.2 no water changes no additions or subtractions my phos dipped to .03 from .05 and my nitrate held steady at 3.5 salinity same at 1.025 Ph at 8.4 will the all and calcium swings be a problem Quote Link to comment

You could repeat the test multiple times in a row and the results could vary more than that. The calcium and alkalinity numbers are harder to explain (as the results are fairly significant). Initially I'd suspect a testing error, although not necessarily a problem with the kits themselves. But I really don't know. At that pH, you shouldn't see increases in both alkalinity and calcium. 1 Quote Link to comment

This has to be a testing error and can't be related to pH due to the massive unbalanced increase between calcium and alkalinity. If his calcium increased by 10ppm while his alkalinity increased by 1.2dkh, I would be quite intrigued. But, since it increased by more than 10x what it would have relative to alkalinity if it were pH related, it simply can't be. OP, what kits are you using to test your tank? Quote Link to comment
Pbalz Posted February 3, 2021 Author Share Posted February 3, 2021 I tested again and number are right I wonder if last weeks test were wrong 1 Quote Link to comment

But the more we get used to using each of these test kits, usually the better (and more consistent) we get at it. When I get a result that I'm not expecting, I usually repeat that test. None of us are totally immune from occasional user error. Quote Link to comment
Pbalz Posted February 3, 2021 Author Share Posted February 3, 2021 Ok but I looked back in my life and alk has been up and down by.5 to .75 is this normal Quote Link to comment

Pbalz Posted February 5, 2021 Author Share Posted February 5, 2021 I was doing 30% once a week using ocean water j use Hanna testers and seifert amonia and copper kits Quote Link to comment
