So i decided to add a bag of Kent marine activated carbon to a mesh bag in a high flow area of my sump. I added this because everybody i talk to uses carbon and says it's a great addition. So i figured it's another way of purifying the water and removing organics and contaminants. I woke up this morning and most of my sps retracted their polyps. granted the lights haven't gone on, most of them have polyp extension throughout the night. My lbs looked normal (frogspawns, acans, candy cane) My anemone also shriveled up more than normal for the night. it does this from time to time but it's fine every time.
I used about 1/4 cup of the carbon. directions said 1/4 cup for 100g. I have a 75g mixed reef tank so i figured with the sump volume i'ld be just under 100g.
I checked my alk this morning and it was around 8.6 usually it's up around 9.8-10. Is alk usually lower in the morning or could the carbon cause this? Also did i dose too much carbon? should i remove it? I guess I kicked myself by adding this. The tank was doin great except a few one or two sps that could look a little "nicer". I"m gonna be home around 4 and see how the tank looks. Any advice on this subject is greatly appreciated. thanks
