The item that I bought at the store supposedly removes ammonia, chlorine, and chloramine. I've got about 35 gallons of RO/DI water in jugs right now, I just don't have any of it mixed.
I felt like I was following the directions fairly well on the FWE. I had a small water change ready (albeit not large enough), a pound of carbon, and I siphoned worms before during and after. I don't have a phosban reactor or a canister readily available, and I don't really have the extra funds the get one at this point. I was hoping that a higher flow area through my sump would suffice. I guess we learn from our mistakes. I haven't had a close call in a while. Just an unsightly mess of flatworms.
I fed a bit of enriched brine with some vitachem and selcon before the lights went out, and both fish ate well. Some of my polyps were beginning to open back up before the lights went out, but I also noticed that some of the flatworms made it through the treatment. I'll further investigate the situation in the morning. Isn't this fun.
