## Questions & Answers

**Q: Do you used these pads in addition to carbon media pellets or do you use these pads without the pellets?**
A: you do not have to use any extra carbon pellets but i add a small bag to the same section as the filter just because i dont have to change these filters as fast so the extra carbon helps with clarity of water

**Q: In what order do you put these filters into your sunsun canister? I’ll be putting these in a 303b model, which only has 3 sections. Thanks**
A: The Order of your filter media is of GREAT IMPORTANCE! First you need to know the direction of water flow through your filter. Some filters are top to bottom, some are bottom to top and some are outside to inside etc. 
You always want the dirty water to hit your coarse foam first, then medium foam, then fine foam and finally your polishing pads. Then, after the foam pads you put your biological media stones. 
You want to get as much of the debris out of the water before it hits your biological media so that it does not clog up the pores of the stones. The bacteria needs to be able to get into the fine pores of the stones and the more water flow you have across the stones the more effective the biological bacteria will filter the water and neutralize the nitrates and nitrites. 
It makes a significant difference which order you put the media! If you put your media in the wrong order you are preventing your nitrogen cycle from functioning at its most effective rate and creating a toxic situation for your fish! 
Remember Coarse foam to fine foam, then polishing pads, then bio-stones. 
Rinse your pads at least once a month and replace the polishing pads.

**Q: Will this filter kit work on my sunsun hw-402b canister?**
A: I think the filters are a little different size. If there to big you could trim them to size with scissors.

**Q: How long does the carbon, ammonia, phosphate filter last? Before it needs replaced**
A: Hello, they should be replaced about once a month, thank you.
