Unless your tank gets below 50, you probably won't ever need a heater. I only use them in tanks with heavy breeding and in areas where I can't keep things 60 and up.
Oh. I see. I'll quit using the Prime then. Don't want the TDS to get outta control there.
I'll take out the heater. I just remembered that CRS do like the temp to be low.
