So, I've run into a little problem. My planted 10g which has been up and running for about 3 and 1/2 weeks now started off great. My sword started showing new growth, and after the first week my crypts seemed to double in size. It seems though that all of a sudden two of my crypt plants are "melting" or dying off. Half of the plant looks like it just melted away and died and some of the leaves that are left are kinda clear looking. The other two crypts in my tank are doing great, nice size, seem to be growing well. Is this normal? I've heard of crypts "melting" but don't they usually do that right after being planted or moved? Should I keep them in the tank, or should I remove them?
Info on my tank- I dose Seachem Flourish once a week, 15% water change once a week, and I also use Seachem root tabs. My light is a T-8 G.E. Daylight, on about 8 and 1/2 hours a day. Any ideas anyone? Am I doing something wrong?
