I would believe so. Reputable guy in our area that runs a really good store. He’s been great to deal with on this matter, and I plan on having him install a 2000g tank into our new home build. He’s been nothing but honest during this but mentioned that we could run carbon to remove the copper? Is this accurate? I love reef tanks but know very little about keeping them up. We pick fish and corals we like by what my 6 year old sees at the fish store. We of course make sure they are compatible.
Yes carbon will remove it but much slower than cuprizorb+poly filter. Even with cuprizorb+poly filter you are looking at about a month or even longer. I've never tried zero copper and a reef with just carbon alone. Running it in a reactor is also much more efficient, whether you use just carbon alone or cuprizorb. If you don't have a reactor I'm sure the store could loan you a reactor and pump you could easily drop in your sump.
