How to use a Hanna Checker.

I thought we would share some pics that we took while playing with the kit here.

Here is a snap shot of the phosphate kit:



And the contents of the box



These things are crazy easy to use.
This is how it works.
The kit comes with 2 glass vials. One is the reference the other you add the reagent too and test for phosphates.
fill both vials with ml of water.
Add reagent to one of the vials and shake for 2 min



Press the power button until the tester show the above image.



Place the vial of just tank water in the checker, press the button and close the lid.
The checker will flash with dashes while it calibrates.



When you get the msg above you are ready to add the second vial containing the reagent into the checker and close the lid.

The Hanna checker will turn off after 2 min of standing idle, so mixing this vial at the start is easier than trying to mix at this step.



Hold the button for a few second until this timer starts to count down.



Unfortunately for this test our water quality in our sps system is impeccable so its not a very dramatic result but a good one none the less.

Zero phosphates even with heavy fish bio load on this system. Big thanks to the Fauna Marin Ultra Phos, Two Little Fishies carbon, giant skimmer and weekly water changes with Royal Nature salt



We did have some detectable phosphates in our LPS system. Not bad though considering we only do 50g weekly water changes and the LPS are currently being quite heavily fed with the Fauna Marin LPS food.

I think I will add a TLF 550 reactor tonight and some phosban media

Great thread! What about the other ones? (Calcium, Alk, etc..)
