Copper in the water

[Kerrymann]

COPPER I know it should be ZERO, my tank holds 800 liters with the sump, just done a test and came up with 0.20 ppm copper, how bad is this?

if this is a troll, you should add more copper to your tank, it will help growth and color on your corals and fish will love extra copper in tank.

If it's just fish only with live rock it will be fine more than likely. But I would recommend finding were it came from and remove source and from tank. OP posted similar question in introduce yourself sticky. Welcome to the forum in any case.

PolyFilter can bind and remove copper.

 

[Dr. Reef]

on serious note, use polyfilter or products like cuprasorb and run carbon along with water changes. all these methods will remove copper from the tank. but you still need to find the source because these remedies will take copper out but if there is a continuous source you will always be fighting it.
