I havent used salifert in the last two years. I didnt know they could test pH and came with a referance sample. I thought only Seachem did that?
To bring your alkalinity down just shut off your calcium reactor and kalkwasser reactor for a few days and it should come down quickly on its own. Test daily to make sure it doesnt drop too low. To speed up the process do a water change. When you start them up again you may want to lessen the flow through the reactor some more.
Another way you can check the accuracy of a test kit is to test some newly mixed saltwater. Your results should be similar to these http://reefcentral.com/forums/showthread.php?t=1714505 |
Although SPS might not be hit hard by a single ALK swing with a ALK swing from 6-7 to 12-13 you will start loosing any zoa colonies you have in the tank. They are a great indicator to ALK changes for some reason.
