How to Acclimate Sensitive Fish

I just received a shipment of cardinal tetras. See how I adjust them to proper temperature and pH using an HM digital meter. The meter itself might be inaccurate, but it doesn't matter because we're concerned more about differences than absolute measurements. By the way, cardinals can suffer heart attacks when be transferred from one tank to another, so make sure to equalize water parameters before moving them. Make your measurements on both tanks with the same meter in order to avoid inaccuracies. 

Correction: there's no chlorine involved here. But the ammonia threat from isolation during shipping is real.
