The bacteria should be fine, I recommend Prime as well by the way. Using that much shouldn't harm anything, you should be fine to carry on as normal (but use less water conditioner in the future).
The light works... it took a 24" "T-8'" bulb. The store had a buy one, get one sale, so I have a spare. One of the two won't stop flickering, so I'll get a replacement.
CASCO just called me (I called them last week) and told me it takes a 24" T-12 20 watt bulb. A T-8 bulb voids the warranty.
I am really mad! I did hours and hours of research, and am now out $13 because they cannot even tell the customer something as simple as what lightbulb it takes. They must think customers are psychic. Their documentation only says "20 watt", nothing else.
ABSOLUTELY DISGRACEFUL!
On a plus side, the rep said 3/16" off level corner to corner is no problem at all.
