Rectangular Pond

How many litres are in my pond?

To calculate my pond volume, enter the dimensions in the boxes. Press 'Calculate', and the volume of the pond will appear in Litres below.

Why should I calculate my pond volume?

The volume is a guide to the pump and filter size you require for a healthy pond. It will also help you with the amounts to dose when using maintenance products.

Pond volume: {{amount}}


Circular Pond

How many litres are in my pond?

To calculate my pond volume, enter the diameter and depth in the boxes. Press 'Calculate', and the volume of the pond will appear in Litres below.

Why should I calculate my pond volume?

The volume is a guide to the pond pump and pond filter size you require for a healthy pond. It will also help you with the amounts to dose when using maintenance products.

Pond volume: {{amount}}

What size pond liner should I buy?

Pond Liner

Enter the dimensions that represent the longest, widest and deepest dimensions of your pond. This is to ensure that the pond liner covers the required area including some for overlap for the edges of the pond.

Please see our complete range of Pond Liners, including PVC Pond Liners, EPDM Pond Liners and Underlays.

Based on the information provided, you will require a pond liner size of:

{{amount}}

How much pond sealer do I need?

Pondshield Pro Pond Sealer

Pond sealer comes in a Single Part (Pondshield Starter) and a Two Part (Pondshield Pro). Pond sealer can be used to seal concrete ponds, to coat flagstones, waterfalls and other concrete structures.

To achieve a strong seal, 2 coats of Pondshield Pro will be required for a total of {{proAmount}} L

Pondshield Pro comes in two parts, A & B, so add the volume of both parts to determine the total for the product (ie, 2 x 2L = 4L Pond Sealer)

For a budget option, 2 coats of Pondshield starter are required for a total of {{starterAmount}} L

The Aquaponics Water Test Calculator will help you decide what products to add to your aquaponics system to ensure the water is within safe ranges for your fish, regarding ammonia, nitrites, nitrates, pH, GH and KH hardnesses. The products we recommend are safe for use in aquaponics systems with fish. When adding new fish to an aquaponics system it is important that the water quality is within the ranges specified in the tests below, so that your fish are not shocked by any sudden changes.
 
The aquaponics water calculator is colour coded to the water test kits that we have available. Please click here to view our range of Aquaponics Test Kits. Once you have tested your water with a test kit, you can come back to this page and input your results to diagnose problems with your aquaponics system. The calculator below will tell you exactly what steps you need to take in order to fix the water quality problems with your aquaponics system.

What pump flow rate do I need for the waterfall width?

Please enter details in the field and the results will be displayed below.

For a projecting waterfall, you need a flow of {{PWAmount}} L/hr (LpH) This flow will ensure the water will leave the wall and project out into the pond.

For a sheer descent waterfall, with no projecting sheet of water, a flow of {{DWAmount}} L/hr (LpH) is required


For higher flow rates, the water will project further into the pond or pool.
Check the pump performance chart to determine which pump will provide adequate flow at the height of the waterfall. Add 30% to the head height to account for sharp bends in the waterfall pipe and losses inside the tubes. Internal diameter 38-40mm pipe is recommended.

Please enter details in the field and the results will be displayed below.

Grow Room Size

Fan Parameters

 

 

Total air replacement in your grow room is every:

{{amount}} minutes

Good, your air replacement rate is under 2 minutes which is ideal for plants. The recommended air replacement rate is 2 minutes or less.

Warning, your air replacement rate is over 2 minutes, you should increase the airflow in your grow room. The recommended air replacement rate is 2 minutes or less, this is ideal for plants.

In smaller environments with high light levels (high heat output in a confined environment) you will ideally want to increase the airflow levels to ensure complete air replacement every 30 seconds. This is due to heat rising significantly faster in smaller environments. Eg. a closet with a 600 watt light etc.

 

 


Bigger filters represent better value for money in the long term and allow for better airflow (less percentage of air loss with the same fan).

 

Larger filters require less pressure than smaller filters because there is a greater surface area for the same volume of air to move through.

 

For approximately 30-35% more retail cost you can purchase twice the carbon (ie. twice the life span) and improve your airflow too.


Fan Speed Converter

Convert fan speeds between units by filling in one field.

Other Ventilation Information

The tighter the bends are in your ducting, the lower the ventilation flow will be. Try to smooth out your bends as much as possible, and make them more gentle to increase flow.

 

What flow rate do I need for my pump and filter?

PondMax EVO2 Pond Pump

Enter the type of pond, the size of the fountain (if any), the number of litres of water in your pond and press calculate. The required pump flow rate for your pond will be shown.

To prevent algae and mosquitoes, consider an easy to maintain pond pump and filter combo. For a budget option with higher maintenance, you can combine a pond pump with a pump pre-filter and algae treatments.

Based on the information provided, your required pump flow rate is:

{{amount}} per hour (L/hr)
