Awesome!! I looked up hornwort online and found that almost all sites say you only need about 2 watts per gallon, so I got some, and it is very cool. Problem is that a few snails hitched a ride to. I got all that I could find out and put them into a water bottle. Once I have found that there are no more snails (waiting aa few weeks to see if I find any) I will add ONE. That is all though because I don't want an infestation! The tank is lookin' good, and my heater finally came, and is keepin the tank at a steady 75. Finally everything is coming together!!! it has been more than three and a half weeks, so I just wanted to ask if there were any signs that the tank is done cycling that I should look for. Thanks a ton!!!!
