Changing coppers

[chrissreef]

I've ran Cupramine but would like to swap to Copper Power (less harsh on fish?). I just bought a Hannah checker and it shows .13 copper still (after doing nearly 40g in water changes over a few days and running carbon for about 2 weeks).

Does anyone have any advice? I have a feeling the readings will be off if I swap now. I need to QT some fish and am debating just keeping cupramine.

Thx for any tips.

Poly filter is better for removing copper than carbon.

I would get the ionic copper out or below .05ppm before you start chelated copper (copper power)

Sean sells a cuprisorb to remove copper.

Can you do a 100% water change? It's a lot more effective than doing multiple smaller water changes.
