it has a weekly trim i have alot of stem plants which i want to replace due to the work i have to do to keep it in check although i quite like the wildish look it gets from time to time , i still have a lot to learn about layout and fertilisers and could do with another light unit for it so i can get the bottom to cover over , it's quite a deep tank at 24" and getting light to the bottom is a bit of a problem .
cheers
