I recently purchased this filter and so far I am pleased. The filter was larger than I anticipated with the ability to hold more media. As it mentions it have 4 trays. As part of my set up, I have 1 tray with 500ml Seachem Purigen, 1 with ceramic rings and Matrix stones, 1 with charcoal and 1 with bioballs. All came with the canister, except the Seachem products which I already had. There are several reviews on youtube you can check out. The best part is was only $43 on amazon. I will update after I have had it running for a few weeks.
