Mr. Saltwater Tank TV Friday AM Quick Tip: One Easy Way To Increase The Accuracy Of Your Water Testing
If you are going to make the effort to test your tank’s water parameters, make sure you are doing all you can do to make the test meaningful.
People always ask me what test kits I recommend, which is why I have my recommend test kit list

Hey Mark,
As always excellent advice. I also remember you once stated you do not like swing arm hydrometers vs. refractometers. Well I found out first hand why, as I was initially using a swing arm and getting good readings (1.024), but I was still getting a lot of livestock death, and all my other parameters were normal. Then I invested the $40 in a refractometer, a minimal investment for what I found. And lo and behold my SG was 1.034. In the garbage went the swing arm. Thanks again for all you do for us reefers
Hi Mark. First off, thank you for all you do to contribute immensely to this hobby (i.e. second job :)). You recommend the seachem ca test kit but the readings are in 50 ppm increments (i.e. 350, 400, 450). This is not very accurate. Am I misunderstanding something? Is there another ca kit that you might recommend? Thank you!
Mark…if your Ca is 400 or 450, it won’t make a difference in your tank.
