starvation hurts doesn’t it? There’s nothing worse than seeing a plant go downhill and wondering why…
Common emails to me are customer sending in pictures of their plants and wondering what is wrong with them. It’s very clear in most cases that it’s a nutrient deficiency and I often wonder why hobbyists limit food for plants and then wonder what’s wrong with them. We all know by now that excess nutrients DO NOT cause algae, so it begs the question, why would you ever limit their food? This problem stems from years of incorrect advice floating around the web and forums. If you want a successful planted tank (and I know you do), give your plants plenty of food.
If you see algae in your tank, the answer is not to limit the nutrients. Algae can thrive in a tank with zero nutrients so quite why some hobbyists think limiting nutrients is the answer when they’re doing just fine without! If you see any leaves that are shaped a bit odd, or they have holes in them or they’re not growing quite right it’s because they need more food! Simple as that. There are lots of different brands available (email me if you want one I recommend), and some are much more simple to dose than others but which ever brand you choose, give it plenty. And don’t forget the dosage on the bottle is the starting point and you only ever go up. As your plants grow and become larger, their food uptake has to be increased. Failure to change their dosage always results in plant deterioration.
So my message is short and sweet. Do not limit the amount of food that you offer your plants. If you are running a non CO2 tank, you only need to provide Micro Nutrients (trace elements) and if you are running a CO2 infused tank you need to offer Micro and Macro Nutrients (Macro being nitrates, phosphates and potassium).
