Pond Filter Cleaner Tablets
Keep your pond’s filtration system in top condition with pond filter cleaner tablets, the easy solution for clean, healthy water. Filters play a critical role in maintaining clear, balanced ponds by trapping debris and housing beneficial bacteria that break down organic waste and harmful toxins. However, over time, filters can accumulate sludge and debris, reducing their effectiveness.
Powerful Slow-Dissolving Tablets for Cleaner Filters & Healthier Ponds
Envii Filter Feed tablets are slow-dissolving and packed with billions of beneficial bacteria. These bacteria target common pond filter issues, including the breakdown of organic waste, sludge, and algae that can clog filters. In addition to keeping your filter clean, the tablets help eliminate harmful nitrites and ammonia – by-products of fish waste that can lead to ammonia and nitrite poisoning, endangering your fish and aquatic life.
Long-Lasting Filter Health & Water Clarity
One tablet lasts up to 4 weeks, slowly releasing beneficial bacteria to keep your filter working efficiently. This extended support improves water clarity, reduces organic waste, and promotes a healthier pond environment. Whether you’re replenishing existing bacteria or introducing new strains, Envii Filter Feed ensures your filter stays in peak condition, contributing to clearer, healthier water for your pond and fish.

FAQs
- 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.
