Help needed (again) Using cuprisorb

citymouse · May 7, 2019

Hi,
So because I suck at all things math, I wanted to confirm if my info is right before adding cuprisorb.
I have a 20g tank. The directions say to use "250ml for every 150g"...soooo 33...34 ml for 20? Did I calculate right?

Yes, 33.3ml.

Thank you for confirming...I always doubt my math in these situations! lol

Wait..turns out the one I bought is different and looks like it's already bagged to treat a 60g tank...does this matter at all? Can you use too much?
I was reading the directions online thinking they were all the same. This one says to use 100ml to treat 60g, but there's a bag inside. Also no idea how I would measure 33.3 ml of powder. Everything I have is for liquid use (droppers etc)

Well it's a slow adsorbing product, using more will just make it more effective IMO, which is a good thing

I would recommend doing large water changes and then adding cuprisorb to remove residual copper, otherwise you will use up quite a bit more than stated on the label - at least that’s been my experience.

Def working on this, I'm mixing water tonight. But also, working on moving them the a 40 breeder, so that will be a completely fresh tank with lots more space.
I don't care if it uses up the cuprisorb, it's prebagged and I don't plan on reusing it, too much work, it was cheap, it's trash when I'm done
