Filters play a very important role in keeping ponds both clear and healthy. They catch and hold any debris floating in the pond, making it much easier for you to physically wash away. They also contain a large amount of pond filter bacteria that inhabit the brushes, foam pads and media. These bacteria break down organic waste in the filter and remove the harmful toxins associated with this waste.

Slow dissolving tablets to target nitrites and ammonia

Envii Filter Feed is a slow dissolving tablet that contains billions of beneficial pond filter bacteria. We use a blend of different strains of bacteria within the tablets to ensure they target all necessary problems commonly found in filters. Their main job is to target nitrites and ammonia, two compounds that are naturally found in ponds, as they are a by-product of fish waste. These toxic compounds can lead to some serious health problems, in particular, ammonia & nitrite poisoning.

A clean and healthy filter system for up to 6 weeks

Envii Filter Feed slowly releases bacteria into your filter to ensure it remains clean and healthy for up to 6 weeks. By maintaining a healthy filtration system you will benefit from increased water clarity, reduced organic waste and a healthy pond capable of preventing blanket weed. Envii Filter Feed can be used to replenish existing bacteria as well as introducing new bacteria.

Will this improve water clarity?
Envii Filter Feed won't actively clear green or murky water but it will contribute to a healthier pond capable of preventing green water. If you have murky or green water we recommend using one of our green water treatments such as Pond Klear.
Can I use this without a filter?
Yes. Although Envii Filter Feed is most effective in ponds with filtration systems, it is still very effective in those without. Simply dissolve the tablet in a bucket of water and pour directly in to the pond.
Will this eliminate algae and blanket weed?
Similarly to green water, it won't actively target algae but it will produce a healthier pond and remove the algaes food source. If you have an algae or blanket weed problem, we recommend looking at our blanket weed treatments.
