I have a used Korallin c1502 with lid to convert it to a nitrate reactor. Approximately half gallon of aragonite for calcium reactor and 1 full gallon of live sulfur media. I’m also throwing in a jbj C02 regulator that worked fine when I took the calcium reactor off line but does have some surface rust from being exposed to the salty air under the aquarium in the stand.
Everything work perfectly when I stopped using. Look to get $250. for everything shipped to continental US.
