Hi Jonathan,
Everything looks the same this morning. There's no dramatic color change on the polyfilter. Just looks slightly brown from organics. I tested combined iodate and iodine with my salifert test this morning (wondering about iodine poisoning somehow even though I dosed iodide) and the results were colorless, so less than 0.03ppm. I know you said the iodide/iodate/iodine tests may not be too reliable, but I figured it was worth a shot. Any other ideas?
Thanks!
