Chemi -Pure regular results
 

I have noticed a definate improvement in my corals ,mostly in the sps ,since I started using it 5 days ago but how long do people leave it in for ? The container says to replace it after 4-6 months.

I probably leave it in for a good 2-3 months or until I'm at the store and remember to buy it. I use it on a fairly regular basis, however I'm never really sure what its doing for my tank vs. regular carbon :razz:
