I added some mangroves to the fuge today. From what I have read and been told they do a good job of removing No2 and No3. I personally have not used them and was wondering if I could get some feedback from anyone who is using them or has and what was or is the outcome. I am planning to get more of them but wanted some feedback before spending the cash to do this. Tx.

The title should have been using em, not upswing. My dang spell check is driving me nuts !
