On November 4, 2022 I installed a UGF - undergravel filter. They are one of the most controversial filters in fish keeping if you read about them at this link: https://aquariumscience.org/index.php/8-5-under-gravel-filters/ you will see why and the reason they are so good if used correctly. In have enjoyed the use of mine for over 2 years and yes they are a fantastic filter.
