Either my testers are no good or I'm in trouble

[Eddie7144]

Ok , so I tested my water levels just now. I did a 30 gal water change last weekend , I use correct crystals. My results are as follows.
Cal = 520 salifert
Dkh = 5.0 Hannah
Mag = 1500 salifert
This is the first time I ever seen levels this high. All my corals seem fine. sps, lap, and softies. Even my clam and BTA are Good. So are my tests wrong ? Am I in serious trouble ? I have no idea what to do !please help !!

Start with retesting.
Good chance of an error in there.
If by chance the numbers come back the same second time round, make adjustments SLOWLY.
The only one I would really be concerned with is the Alk.

Have a friend or store test your water too. Never act fast always check several times and you might find that the test where wrong. [emoji3]
