I just got plants for my 37 gallon tank and they are starting to turn brown! I have only had them for a few days now and I don't k ow what to do. I tested my ammonia and it was really really high, but I don't know for sure because I have been using dr tims ammonium chloride to fishless cycle my tank(it's still cycling) and I don't think my test accurately test for this ammonia additive. I really don't know what to do and any suggestions to keep the plants healthy will be great. Also, I'm not entirely sure that they are dying, but they are turning brown. I'm sorry but I can't provide a picture since the files are appearently too large to send.
