Looking for Seeded media, as well as "bulk" sized hornwort and American Frogbit . Located in Centreville (VA) can drive within reasonable distance or have shipped.
The coldest shrimp tank I have is about 65 degrees and the top is covered in frogbit. I can bring you a bag of it for free if you want to the next meeting and you can give it a try I usually throw a ton of it away every month it will have snail eggs.
It is amazon frogbit. What temp do you keep your tanks at?
If its American I will totally take you up on it as Amazon frogbit does not tolerate my aquarium cold
I have lots of frogbit can bring to the next meeting if you are going to it.
