I recieved a couple of bundels of HC. I try to push down as much as the roots possible but ended up burying parts of it to keep it from floating. I also sprinkled some gravel on top to help it stay in place. I spread it out in little chunks. My co2 ppm is @ 30 and adding GW fertz 3 x weekly, my temp in the tank is 79 degrees. Whats the max temp it will tolerate? I have discus in there, temp used to be between 81-79. I adjusted the thermometer to set @ 80 but since its an open tank it sits at 79. Is this temp too high for it? Did I plant it right and is everything set for it?Thanks for all the great help!
