You'll remember this photo from my equipment post:
Nothing pretty here.
I turned on the pump without the filter and let it circulate for a few hours. Initial numbers had the pH above 8.6 and TA around 80. I put in around 100oz of acid and got the pH down to 7.5. That didn't fit it.

More waiting, more backwashing. Something is definitely happening in there. Many tadpoles lost their lives this day.

At this point, I need to add some water (from a well) to compensate for all the backwashing. I also don't want to stay up all night with this baby, so I decided to up the chlorine a bit, set the filter speed to medium and call it night. It's raining, if that matters.
