NT LABS Zeolite 5kg

NT Labs Zeolite is commonly used in pond filtration systems to help absorb and remove ammonia and other nitrogenous compounds. Recharging the zeolite helps maintain its effectiveness over time. For best results, use NT Labs Zeolite throughout the year and recharge it regularly. Consider recharging and topping up when water quality begins to decline. Read more

How to use:

1. Place the zeolite into the filter bag provided and rinse it under the tap.
2. Position the zeolite in the filter in an area with a strong flow of water.
3. Test your water quality using NT Labs Test Kits regularly.
4. Recharge the zeolite in spring and every 6 weeks unless poor water quality is detected. When recharging, replace 50% of the zeolite.
5. To recharge, prepare a salt solution (4 tablespoons per gallon of water) and soak the zeolite chunks for 24 hours.

Vortex Brushes

Vortex chambers are good for settling out heavy waste but much less efficient with the lightweight particles. Have you noticed that even though you get a lot of waste in the bottom of your vortex, you still find that the subsequent chambers get very dirty too. This is the very fine particles that do not have time to settle in the vortex and so they get drawn through the transfer port into the next chamber. First, they physically trap the large particles that cannot pass through the close weave of the interlocking filaments. Secondly, the filaments have a static charge that ‘grabs’ any small particles that are flowing by. This charge holds onto the waste until you do your routine cleaning. Thirdly, after you have been using the brushes for a few weeks, the massive surface area of the brushes becomes home to millions of beneficial nitrifying bacteria that will help to purify your water biologically.

Media Grids

Media Grids are a most useful aid for anyone building their own filtration system these can be placed at a level that provides a void of water underneath the media itself and keeps the media out of any debris that may have gathered in the filter. It supports the media and is quite robust and is a must really can be fixed together and cut to size using simply a fine toothed wood saw or angle grinder. Read more
