Sera copper test kit and polyfilter
Has anyone had any experience with the Sera copper test kit? I decided I
had to know if my tank had residual copper from a big ulvaceous before I
sacrificed any additional shrimp. Of course I don't know for sure that was
what took them out in the first place.
Obviously, the time to check for copper would have been BEFORE I started
doing a bunch of water changes.
Sera was the only kit the local places had. I also bought a polyfilter to
check the kit. I wasn't familiar with it but it absorbs various elements in
the water and turns different colors depending on what it has absorbed
(copper is blue). Sera test indicated 0 copper and when I stuck some of the
polyfilter in a filter for the day, it absorbed the iron, I didn't think I
had, but no copper. Just thought I would share about the polyfilter since
it seems like a cool product for diagnosis/removal of undesirables. I
believe it is a popular product with the saltwater folks. It seems, at
least in this instance, that the Sera kit was correct.
