Thank you so very, very much for all the great information. Hopefully I will be able to salvage some of my macros. Incidentally, I thought it was neat that you recommended Inland Aquatics. I bought my macros from them, because they’re very hard to find locally. The customer service was fantastic, and the plants were in beautiful condition when I received them–too bad my good intentions killed them:blush:….I would definitely order from Inland Aquatics again, maybe try some of the other macros you suggested.
