I have a Hayward star clear 200sq cartridge filter. It's only 2 years old. It works like a charm. It's set up with a pentair inteliflow pump. The problem I have is when I do a vacuum fine debris bypasses the filter and comes out. I clean the cartridges every 2 months. Use tsp over night and light acid cleaning. Have two cartridges and swap them out every 2 months. The issue works on both. I have tried clipping a piece of cloth and zip tying it around the internal clear in pipe. Still no joy. I was wondering if there is a small post-filter I could put on my set up. Maybe the Jandy Energy filter. To help catch the fine debris. What do you think? Anyone else have this issue. I wouldn't consider switching to DE. Cartridge works fine on a 15k I ground pool.
