The eheim on the korallin still needs to be used as a recirc pump to dissolve the co2 and keep it flowing. The feed pump is the peristaltic. The peristaltic is only a feed pump. It does not matter if it pulls or pushes the effluent, its the same. Pulling is just safer.

int = internal
ma = current controlled from external source
v = voltage control from external source

Unless you have a controller that you want to use to change speed and remote start/stop the unit then int is the correct setting.

Hobby Experience: 9200ish gallons, 26 skimmers, and a handful of Kent Scrapers.

Vortech Powered 600G SPS Tank w/ 100gal frag tank & 100g Sump. RK2-RK10 Skimmer. ReefAngel. Radium 20k.
