I’m really confused. You’ve mentioned a scopas tang, wrasses, I saw a hippo tang, an orange shoulder tang, a blenny, and your water has been doing some big swings and I see Marine Buffer, magnesium, All-for-Reef, Seachem pH and now your ammonia is rising, and you’re now trying to combat it with a pad and matrix … my question is if this is all happening in just one tank? If it is all happening in one 10g tank it boggles the mind! AfR is for tanks that already have an established consumption rate and won’t stabilize out of wack mag/cal/alk. In tanks that small 20% weekly water changes should be enough for startup. Tangs poop a lot and can overload a new tank pretty quick even with a sizable sump. I don’t think your tank has been set up long enough to handle what you’re throwing at it. Hope your tank prospers!
