I’ve been using this filter kit for two months now. The water flow is smooth and the filter doesn’t get clogged easily. I only need to clean it every two weeks, which is much better than before. The placement order works well and I didn’t have to adjust anything initially.

The handcrafted cotton is easy to handle and fits perfectly in the Tidal filter. I used one piece at first and it worked fine. After a week, I noticed a bit of white turbidity, so I added a second piece. Now the water stays clear and the tank looks cleaner.

As a beginner, I was worried about maintenance. This kit solved that. The instructions are clear and the filter stays clean longer. I didn’t have to cut the cotton myself, which made it very convenient.
