Its fast-acting, gel-based formula adheres directly to filter media, ensuring efficient colonization and optimal pond water quality. Safe for all aquatic life and backed by multiple UK industry awards, it’s the essential start-up treatment for new ponds, seasonal restarts, and post-chemical recovery. ## Description Product Description Why do I need to use PURE+ Filter Start Gel? When starting up a fish pond, the media will start to mature only once the fish have been added and the result of adding fish means that the water parameters will change. The breakdown of food and fish waste will create spikes in your ammonia and nitrite, but adding the Filter Start Gel will help to balance this. The gel converts the ammonia and nitrite so that once the fish have been added, your media will mature quicker and reduce stress levels, resulting in a healthier pond. With many ponds being under-filtered, PURE+ Filter Start Gel can assist with the survival of fish too, this is because the blend of different bacteria can help keep the fish alive, even during horrendous conditions. When to use PURE+ Filter Start Gel When starting a brand new pond - PURE+ Filter Start Gel speeds up the maturation of filter media giving your pond and fish the very best start. At the start of the new season - cold weather can kill off beneficial bacteria in your pond. Give your fish a stress-free start to the new season by ensuring that your pond filters are running optimally. When introducing new fish - adding new fish can put a strain on your current filter. PURE+ Filter Start Gel adds billions of nitrifying bacteria that work immediately to rapidly colonise your filter. After harsh chemical pond treatments - chemical water treatments can easily kill off the beneficial bacteria in your pond. PURE+ Filter Start Gel is a natural pond water treatment that is designed to rapidly bring your pond’s ecosystem back into balance. How to use PURE+ Filter Start Gel Adding to a new pond Shake well before use to ensure the bacteria has not settled. Unscrew the cap and pour the contents of the bottle directly onto your filter media for best results. You cannot over-dose your filter with gel. We always advise the addition of oxygen to your pond via an airpump and diffuser when using PURE+ Filter Start Gel. Always perform regular water tests using a suitable test kit, especially before adding fish to the pond. If a UV-C is running, switch it off when dosing and keep switched off for 12 hours after dosing. Adding to an established pond The good bacteria you have accumulated over the summer months will have been affected, due to the cold weather conditions over the winter period. It is encouraged to use PURE+ Filter Start Gel on your media once your fish start to feed again, this ensures that the ammonia and nitrite do not spike during this time, keeping your fish healthy. Top up your filter with the gel after each maintenance when cleaning your filter.
