## Questions & Answers

**Q: Does it come with filter media**
A: Yes it is supplied with filter media ready to set up.

**Q: Is this supplied with a uk plug?**
A: No. Mine arrived a couple of weeks ago with European plug and i bought a cheap converter plug.

**Q: Does this come with the pipes?**
A: This comes complete with a length of pipe that you cut to fit your setup and all fittings and media for the trays are also included. Hope that helps.

**Q: Could you tell me if the inner hose size is 18mm, (I.D) or what size the external connectors are. Thank you in advance.**
A: yes they are the larger 18mm pipe work, although i have started mine with 100mm of 18mm then used reducers to take it down to the smaller gauge stuff which is not a problem as on the filter itself there is a control to reduce the flow rate, i done this so the return water to the tank was not so fast and agresive, hope this helps
