Chlorine & Sediment Remover (Attach to your garden hose!)

Chlorine in tap water can be a major threat to your plants. Sure, it's added to kill germs and purify the water, but it can lead to sickly plants with yellowing leaves, stunted growth, and even death.

For hydroponic growers, our hydroponics for beginners guide explains water quality alongside pH, EC and system basics.

 Instructions

• Make sure to screw in your adapters firmly, but do not over tighten!
• For maximum filtering efficiency, use a flow rate of 2L per minute. Filter can be used at a maximum of 9L per minute.

• Make sure to connect the inlet to the correct end as marked.

• On first use, run the unit for 2 minutes to settle the filter contents.

• Store the filter in an upright position to allow the unit to drain in between uses.

• Replace your Dr Greenthumbs water filter after 12 months of use.

• Please note; connect the hose to the end that has the ridge on it, so the flow is running the same way as the arrows on the filter. The flow direction is clearly marked on the filter if you are confused.

Please Understand - These filters are not intended to be dragged around on the end of a hose; if you would like to use the filter connected to your garden hose, please connect it at the tap end and secure it in place (we sell mounting clips for this purpose) before connecting your watering wand/sprayer end.

If you plan on using your water filter connected to a garden hose, it is best practice to secure the hose so no undue pressure or stress is placed directly onto the plastic connector. If you are unable to secure the hose, click here to buy brass connectors.
