Since adjusting the photoperiod, things look better in both tanks. It looks greener. The crypt wendtii, which I was starting to feel concerned about, is showing its blue-green hues again (hard to get in a photo).
The water wisteria wasn't doing well in this tank for some reason, I've moved what was left into the tenner. Floating watersprite never seems to do well either, I had tons of tiny bits that just have not been growing. So this week I tossed all those and instead left pinched off hornwort stems (side shoots) as floaters.
