Advice Needed: Plants Seem Not Healthy
Hi, I am new to this hobby. I just got the newer version Fluval Edge 6G with LED. I put in some amazon sword, java fern, java moss, and dwarf hairgrass. I noticed that some of the amazon sword's leaves are getting transparent on their tips and some brown spots on the leaves of the java fern. Is the water toohot/cold or something wrong? I have the Tetra HT-10 50W heater. I have a stick-on thermometer which shows ~25 deg. I didn't have any fish yet, just 3 cherry shrimps for now. Any help will be greatly appreciated. Thanks.
