Seachem Multi Test pH and Alkalinity - 940

Whilst slightly more expensive than other oH and Alkalinity test kits on the market, the Seachem MultiTest pH and Alkalinity can be viewed as a professional test kit with the appropriate equipment being provided. This includes:

- Marine pH Reagent
- Alkalinity Reagent
- pH Reference
- Alkalinity Reference
- Stir Rod
- Alkalinity Pipette
- Sample Pipette
- pH Colour Chart
- Test Plate

Testing pH:

1) Fill sample pipette to base of bulb and dispense to a test cavity of the test plate
2) Add one drop of Marine pH Reagent and stir briefly
3) Read pH from chart

Testing Alkalinity:

1) Fill smaple pipette to base of bulb and dispense to a test cavity of the test plate
2) Hold the alkalinity pipette vertically and add 1 drop of Alkalinity Reagent. Stir briefly. Continue adding drops (count the drops) and stirring until colour turns from blue to yellow. Just before going to yellow, a lime green colour will appear. The final drop is usually one drop beyond this point.
3) Each drop is equal to 0.5meq/l. The number of drops to get to yellow divided by 2 is the total alkalinity.

Reference Test:

The proper performance of this kit may be validated by running a test in the normal manner exvept that a reference sample is used in place of the aquarium sample. It is not necessary to run a reference test to use this kit. The only time you might choose to run a reference test is if you have cause to believe the test if giving incorrect results. If you run a test using the reference sample and obtain the corrrect result then you know the test is working as it should.
