Interesting... I think I have 4 jars of those ceramic rings sitting in a box somewhere untouched. If your lithium stops rising they may remain untouched. If it keeps rising they'll likely remain untouched...Lithium has been steadily rising in the tank. After some "research" and process of elimination think it may be from the ceramic rings I won from Algae barn a few years back. So I removed them from the sump. Which led to cleaning the sump which led to a mess. The tank looks like crap since I stirred up about 6m worth of mulm/detritus. Sucked most of it out but it is still gross. Hopefully everything is settled by morning. Note to self : Need to make some fresh saltwater to have on hand for oh poop moments.
Night.
