I previously dosed lanthanum chloride (Phosphate Rx) into a 10 micron sock without issue. Two days ago I administered a half dose into my overflow which subsequently filtered by a 200 micron RedSea Reefmat. The next morning I woke up and found my Yellow Tang laying on its side on the sandbed breathing very slowly. I removed the tang and put him into a bucket with heater and air stone for observation. Unfortunately, the tang died 15 minutes later (stopped breathing completely).
My One Spot Foxface was best buddies with the Tang and has not been taking the loss well. The Foxface was hiding in the rocks all day yesterday. In the evening, the foxface swam around the tank like a speed demon banging into the rocks and display glass. The Foxface eventually went completely upside down on the sand. After about 10 minutes the Foxface righted itself and went back to its normal hiding spot and seems stable for now.
If anyone is considering dosing lanthanum chloride you should only consider doing so with the appropriate precautions if you have tangs. Going forward I plan to administer a half dose (or less) diluted with 350ml of RODI over 24 hours via an IV bag drip into a 10 micron sock which receives heavy flow via a return manifold in my sump. Slow drip setups are cheap on Amazon if you look for plant watering setups ($6 for 4 bags which are reusable).
Learned my lesson the hard way unfortunately.
