Review: I think it's actually working! - After trying a number of different aquarium plant fertilisers to no avail, I was surprised to finally find something which seems to actually work. I added 5ml of API leaf zone twice a week into my 87l aquarium. After 3 weeks I have noticed my desertcart sword plant looks much better! More green and growing new leaves. Other plants seem to respond positively too. I'm especially glad about the desertcart sword plant. Previously, the leaves were dissolving, full of holes and covered in brown diatoms. It's so much better now. I hope it improves even more over time. I like the leaf zone fertiliser has only iron and potassium in it and no nitrate. I tested the tap water and it is high in nitrate. Therefore, it seems my aquarium plants needed a fertiliser without any extra nitrate. Too much nitrate can cause problems, including growth of diatoms (brown algae). I also want to mention I have amano shrimps and panda cory fish and they seem to be unaffected by the fertiliser. I think API leaf zone is very good. Try a small bottle, it may do wonders to your plants. Hope it helps.
