One suggestion if I may, ditch the Schuran Jet1 and buy a GEO.. You will thank me later. The schuran is the biggest POS I have ever owned. Customer service is non-existent. I sold my Jet1 and bought a 6x18 GEO and the difference is night and day. I set my GEO up in 10mins, T'd off my return.
The Schruan thread is littered with problems, breaking parts, leaking reactors. the wing nuts are on the top and bottom of the chamber are the biggest PITA to remove, you have to drain the entire reactor to add media.. man the list goes on and on for me.. Please read up on the Schuran, and seriously consider the GEO.. Again your will not regret it.
