Wow everyone, thank you for the responses..I am glad I am not alone! Along with the posts on our forum I also received a couple of e-mails from individuals with suggestions. I am going with dosing with CaCl and MgSO4 when I do water changes to deal with my plant deficiency problems. I will monitor the KH (carbonate hardness), DH (General Hardness), and Calcium levels between water changes to see what is happening with the levels. If you want a progress report on how things are going let me know! I did my first CaCl and MgSO4 dosing about a week ago and I am already seeing improvement in the new leaves of my Rotala sp. 'Nanjenshan'. _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
