Pure Filter Start Gel Pond Filter Starter Bacteria - Wildlife and Fish Friendly Water Pond Bacteria Treatment for Filters and Filter Media | 2.5L

I’ve tried many products that has said that they can mature a biological filter but they have ALL failed APART from this one!!!! It’s amazing! It worked within 2 weeks with my Ammonia and nitrite dropping to zero. I’m so impressed that I’ve ordered another just to put a small amount in for water changes etc

Topped up the filter as it didn't seem to have enough bacteria in. All seems fine now.

Used to bring down Nitrite readings which were a little above perfect. All good but takes some time to do this. Product not cheap though!!

Does what it says on the tin

WORKS OK I THINK STRANGE BEING A GEL I NORMALLY USE LIQUID

Good product to boost filters after winter weather and spring arriving.

Great stuff

Quick delivery. It is a good product for the pond- don't know if better than others, but a pond needs bacteria and this does the job

Das Gel verteilt sich gut. Wesentlich besser als die Kügelchen. Kaufe es immer wieder

Ottimo prodotto ma soprattutto 5 stelle al venditore . Dopo aver ricevuto il prodotto nelle quantità errate hanno provveduto subito a spedire il prodotto giusto lasciandomi l' altro in omaggio. Quando un Azienda é professionale 🔝 KoiFranciacorta una garanzia !

Nicht so gut 👍
