I only asked because I wanted your opinion on if they were no3 and po4 factories. I have 4 in my current sump and they only need replaced once a month so its no pain at all. I have a huge BK 250 skimmer on my 185 gallon tank and just know its too much for my system right now. I was wondering if i should take the socks offline so that "food" is circulating in the tank more for the corals and the skimmer will eventually get it.
Thoughts?
