Liquid Test for Alkalinity

(No shelf life due to being a liquid test kit).

This is neither food nor drink so sell by date no problem.

As these have gone past there sell by date of 2017 we are putting 2 Alkalinity test kits in 

with every purchase of this item.





How important are some of these levels?
First of all these test should be done on all/any pools or tubs.

What is KH?

KH, also known as Total Alkalinity or Carbonate Hardness is a measure of the buffering capacity of the water in your swimming pool. The

buffering capacity refers to how well the swimming pool can resist changes in pH.

How do I do the test?

Ensure the test tube is clean. Take a 5 ml sample of pool water into the test tube, to the first mark on the test

tube (approx. halfway). Take the KH reagent and add one drop, mix and the water sample should turn pale

blue. Keep adding drops, one by one (remember to count the drops!), mixing between drops, until the blue

colour turns to yellow. The number of drops needed to bring a the colour change is equal to the KH value in

°dH. Should the first drop of reagent turn the sample yellow then the KH value is below 1 °dH.

1 °dH = 17.8ppm.

Why do we need to test the pool for alkalinity?

PROBLEMS RESULTING FROM HIGH ALKALINITY:

If the Alkalinity of your pool is high, these problems

will occur:

  • • Cloudy water.•

  • Scale formation on the pool walls, floor, plumbing and equipment.•

  • Short filler runs and overall poor filtration - primarily due to scale that is deposited inside the plumbing, which restricts water circulation.•

  • Minimizes the effectiveness of chlorine (or its alternative).•

  • pH will be difficult to adjust.•

  • Eye and skin irritation.

PROBLEMS RESULTING FROM LOW ALKALINITY:

If the Alkalinity of your pool is too low, these problems will occur:•

Dissolved metallic parts of your pool (walls, floor, hand rails, ladders, light fixtures, and equipment). This could even lead to discoloured water or stains on the pool walls and floor.

  • • Stained and etched concrete in concrete pools.•

  • Stained and etched plaster in gunite or shotcrete pools.•

  • Stained liner in vinyl-liner pools.•

  • Blistering or delamination of fibreglass in fibreglass pools.•

  • "pH Bounce." Alkalinity acts as a buffer for pH. If the Alkalinity is low, the pH will fluctuate dramatically. Yesterday, it may have been 7.0, and today it may be 7.8, and tomorrow it may be 6.8-it can change from one extreme to the next, literally overnight.•

Minimizes the effectiveness of chlorine (or its alternative).•

Eye and skin irritation.

Liquid Test for Calcium Test Kit

  (Long shelf life due to being liquid 5 years or longer)

 

How important are some of these levels?

First of all these test should be done on all/any pool.

Calcium - Can leave deposits and scale on your pool and if to low your water can also hunt for added calcium and getting it from grout or concrete etc. Therefore causing damage.

You can keep on top of your water chemistry and if you would like added information on water chemistry please go to our **Water Maintenance info**

Calcium Test KitInstructions on using this test kit:

1. Fill the test tube to the 5 ml mark with water to be tested.

2. Add five drops of reagent 1.

  1. Add one tablet of reagent 2 and mix.

    3. Add reagent 3 one drop at a time, mixing between drops,

    until the colour changes from red to blue. Make sure you

    count the drops required to achieve the colour change.

    4. Each drop required to achieve the colour change

    ie equivalent to

    50 ppm of calcium.

    5. After testing wash the sample away with plenty of water.

    CORROSIVE

    Causes severe burns.

    Keep out of the reach of children.

    In case of contact with eyes, rinse immediately with plenty of water and

    seek medical advice.

    Take off immediately all contaminated clothing. Wear suitable gloves and eye/face protection.

    SCALE:

    Excess calcium in the pool water will lead to a build up of scale that can be readily deposited on the pool walls, floor, plumbing or equipment. In order for scale to be present, an excessive amount of calcium must be present and water chemistry must be out of balance. Scale is obviously unattractive on the pool walls and floor, but it can become a potential problem if it builds up in the plumbing or on the equipment.

    CAUSES OF SCALE FORMATION:

    Scale is a build up of calcium that can be readily deposited on the pool walls,

    floor, plumbing or equipment. Scale will appear as a white, calcified deposit. In order for scale to be present, an excessive amount of calcium must be present and water chemistry must be out of balance - typically either high pH,

    Alkalinity, Hardness, or a combination of any of the three. If calcium is present and the water is out of balance, the calcium will be precipitated out of the water, by either heat or evaporation, and will deposit itself on the pools walls,

    floor, plumbing and equipment in the form of scale.

    Scale is obviously unattractive on the pool walls and floor, but it can become a potential problem if it builds up in the plumbing, restricting water circulation and filtration, or if it builds up on the equipment, causing equipment failure and

    premature replacement.

    It is due to this potential build up of scale that dictates that Hardness, often called Calcium Hardness, must be tested and adjusted.

    HOW TO TREAT SCALE FORMATION:

    If scale occurs, either the pH, Alkalinity, Hardness, or a combination of

    any of the three is

    high. You must test and adjust the Alkalinity, Hardness, and pH - in that order. Then, once water chemistry is in range, a Metal Sequestering Agent should be added to the water to remove the scale. Read the instructions on the label before any application is made. It will also help to brush the scale off of the pool walls and/or floor.

    SHOCK AS IT MAY RELATE TO SCALE FORMATION:

    Since calcium can lead to scale formation and its

    destructive results, if you traditionally have hard water (primarily due to high levels of calcium), you should use

    Lithium Hypochlorite instead of Calcium Hypochlorite to shock the pool. As the name implies, calcium is an ingredient of Calcium Hypochlorite shock.

Liquid Test for Total Hardness

(Long shelf life due to being liquid 5 years or longer).

What is GH?

General Hardness is a measure of the sum total of minerals dissolved in the water. Water can be either ‘soft’ or ‘hard’ depending on the amount of dissolved minerals, (the more minerals the greater the hardness).

How do I do the test?

Ensure the test tube is clean. Take a 5 ml sample of pool water into the test tube to the first mark on the test tube (approx. halfway). Take the GH A reagent and add two drops. Mix and the water sample should turn dark pink. Add one drop of GH B and mix. Keep adding drops one by one (remember to count the drops!), mixing between drops, until the dark pink colour turns to blue.

The number of drops needed to bring about the colour change is equal to the GH value in °dH. Should the first drop of GH B reagent turn the sample blue then the GH value is below 1°dH.

1°dH = 17.8ppm.

Why do we need to test for this balance?

 

PROBLEMS RESULTING FROM LOW HARDNESS LEVELS:

If the Hardness of your pool is too low, these problems will occur:•

  • Dissolved metallic parts of your pool (walls, floor, hand rails, ladders, light fixtures, and equipment). This could even lead to discoloured water or stains on the pool walls and floor.
  • • Stained and etched concrete in concrete pools.•

  • Stained and etched plaster in gunite or shotcrete pools.•

  • Stained liner in vinyl-liner pools.•

  • Blistering or delamination of fibreglass in fibreglass pools.•

  • Minimizes the effectiveness of chlorine (or its alternative).•

  • Foam.•

  • Eye and skin irritation.

 

If these, or any other, problems result due to low Hardness, you must raise the Hardness level immediately,

using Calcium Chloride (which is typically packaged and sold as "Hardness Increaser," "Hardness Up," or Hardness Plus").

PROBLEMS RESULTING FROM HIGH HARDNESS LEVELS:

If the Hardness level of your pool is high, these problems will occur:•

  • Cloudy water.•

  • Scale formation on the pool walls, floor, plumbing and equipment.•

  • Short filler runs and overall poor filtration - primarily due to scale that is deposited inside the plumbing, which restricts water circulation.
  • • Minimizes the effectiveness of chlorine (or its alternative).•
  • Eye and skin irritation.
