Do Plants require a weekly fertilizer to grow? I'm not sure, does it work? I think this was a topic a long time ago but I cant find it so yeah.... My plants aren't growing well probably also as I dont yet have a proper aquarium lighting but will be getting one in the next few weeks from work. Should I get Fertilizer if so what type brand is trusted by you guys? Also what lighting strength etc. for low lighting do I need for my size tank. Will one globe suffice?
