Weak stems in my Water Sprite
My water sprite (Ceratopteris thalictroides) fails to produce long stems and breaks up into floating plantlets. I use ferts including CSM + B but I don't know why the water sprite fails to grow properly. I know that Fulton County has soft water and would like to know if addition of Calcium and Magnesium would help. I have not done that bc I have no data to support that idea. Can someone who has strong growth of water sprite help me understand if or whether this problem has a solution?

As far as breeding SAE's goes, it's never been truly done in intentionally, but every now and then a rare accidental occurrence has been stated in home aquaria, props to you for doing who-knows-what to manage a captive spawn without even knowing you did who-knows-what correctly!
Since very little is known about raising SAE in home aquaria, I'd suggest leaving them in there as long as there aren't any predatory fish or aggressive cichlids since the presence of biofilm and algae from the established birth tank would most likely be best for them to graze upon.
