I have this liquid fertilizer called plantgro. It tells me how much to add to my size of tank but it doesn't tell me how often? How am I supposed to know when I need to ad more to my 33gal? Its all live plants and most of them grow very well. I just don't understand when to fertilize. Thanks
How much plantgro?

The Hagen PlantGro bottle says 5 ml per ten gallon once a week. What it *doesn't* say is whether that is a low light/noCO2 tank or highlight/Co2 or some place in between. I've used it before as you can guess since I read the label when I saw your post. I used it in a low light tank by the instructions. I never bought any more because it seems rather expensive for what you get in it.
OK I checked the bottle again. It is the smae product but it doesn't say -anywhere- to use it once a week. Just gives me the 5mL/10gal part. Maybe I got a misprinted bottle or something. I don't think I will buy it again either. My plants do just as well without it.
