Ultralith Exchange

[b_vanfossen]

Claude-

I have a 90 gallon total volume system. I started off with .5 liter of Ultralith and after 30 days I have just added the other half of the lith and now have 1 liter of lith in my sump.

My wuestion is-
1. when should I do my first exchange?
2. How much do I exchange?

My 2008 manual does not say...

thanks

Brian, I'd suggest changing 50% of the media every 6-8 weeks. Your first exchange should take place 6-8 weeks from the day you added the other half of the UltraLith.
