## Questions & Answers

**Q: Will this fit the marina 360 degree aquarium 10 litre?**
A: Im really not sure. On my filter its a bit small coz i dont know the size of the filter for the reason that my son’s aquarium was given to us

**Q: Will it fit a aqua start 320 the marina125**
A: The information on the pack indicates that it fits the Marina I25 filter specifically,no other filters.

**Q: Is this the correct replacement cartridge for the marine A-131?**
A: When I bought the pump is was it was for i25, so I don't know if it will fit A-131.

**Q: what type of material is in the filters?**
A: The Marina i25 filter Power Cartridge has an initial chamber containing zeolite media which removes toxic ammonia from the water.

The second chamber contains carbon which removes pollutants and unwanted odours from the aquarium water.

Floating debris and waste is drawn into the filter inlet and trapped, all of which contribute towards clean, clearer water.
