Pure Pond are biodegradable balls, crammed full of live
bacteria that are slowly released when they are needed
most. With over 8,000,000,000 bacteria per litre of Pure
Pond Balls, your pond will shine even more than normal,
especially if you add them monthly into the Kaldnes
Moving bed, or into any other type of filter you may have.

How to use it?
When you introduce the Pure Pond balls into the biological
chamber of your Nexus, they become one with moving bed,
agitating alongside the K1 media, just waiting to smooth
out any peaks and troughs of the Ammonia/Nitrite cycle,
to give you even healthier, crystal clear water.
