All makes sense. Thanks so much.Cleaning it doesn’t help. Stop dosing anything for a few days, Keep alk low 7 dKH when you resume dosing, and use bicarbonate to do it. Don’t aggressively lower phosphate, and don’t use gfo. After a while it should stop if you are feeding and such.
Last question... I’ll refrain from cleaning / breaking up the sand bed chunks for now, but am concerned that I’ll create the problem again when I eventually do clean the sand and re-expose the precipitate (say a couple weeks ago, when things stabilize). Will that be a problem in the future?
