HYDRA LT Extreme - Winter Bacteria for Pond & Lakes | Pond Algae Remover & Sludge Remover | Works As Low As 4°C - 500 G

We have Sturgeon as well as Koi so do have to feed 2-4 times a week through the winter. It’s hard to combat any Nitrite spikes in winter so tried this. Amazed! Within 2 days the parameters were back to normal and held steady until we just added some new fish and carried out a course of Chloramine T. Would definitely recommend this and the Hydra Bio Aquatic to keep your parameters as stable as possible throughout the year.

So far so good no problem with this to report

working slowly but surely
