you can simply add a calcium pill in right at the larve , see if they eat on it , and it would help with thier hardness for a little while , just make sure no really rare plant is right beside then that needs full soft water ... woudl love to see ho wthis gies for you , as I have seen many eggs, never any babies ... keep us posted !!
Thanks for the advice. I dropped in a calcium pill and it dissolved right away. Its kind of under the plants that the larvae are on but some floated up and laned back on the plants. Will they eat it or absorb it somehow. I put cuttlebone in too for the adult snail. She doesn't seem to interested in it. Hope it works. I will def keep you posted. This is quite exciting!I'm getting some briggs as soon as they are ready. Just getting into the snails and I love them although the Olive Nerite is the only one I have now. So glad I found this forum!! Many nice people who can help educate me! Wooo!
