## Questions & Answers

**Q: Which direction do I put these filters on the green enclosure? Rougher side towards back, or rougher side towards front? Thanks!**
A: Coarser filter goes to the back so that it can remove the bigger particles before filtering on the finer side. My filter unit has two cartridges so I change one alternately every time I do a water change, every 3 weeks.

**Q: Can someone please measure the filter with a ruler. Several people have asked and no one has answered with actual measurements.**
A: Thank you for asking Penny!  They are 5-3/4" high x 4.5" wide.

**Q: have a filter with red insert carbon filter has to be attached to fits inside of 35 gallon filter  can't remember which filter type it was  help**
A: I would recommend you call our team at 1-800-526-0650 if you think it was one of ours. The red insert could be a bio grid which comes with one of our lines. Also, look at the top of the filter. We mold the model name and size in all of our lids.

**Q: im needing to find the "cage/holder for theses filters. Any one have a Parrt #?**
A: no ..don't have a part...write to the company...
