Outlook: Foggy

Tropical Fish pristine crystal tank, feeder working obviously at the right rate.
Cold fish, as you see. Should I aerate the water or change it?
If I change it does it have any additives or do I just run two pipes, one in one out maintaining temperature?
The feeder may be giving too much how do I reduce the delivery?


Been out on the XBR to do my house sitting duties and then up to Swineyard Hall.
