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 Amazon sword plant looks much better! More green and growing new leaves. Other plants seem to respond positively too.I'm especially glad about the Amazon 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.

Seems to work well, will leave the water yellow for a little bit but no problem will clear up. Plants seem to be doing better and looking greener. No copper so safe for shrimp also.

Great product
My Anubias and Java Fern were growing at a much slower pace since my tank setup is pretty new. I started dosing 5ml-7ml weekly once for my 2*2 ft tank— seeing great improvements in my plants and good number of new leaves already — after 1.5 months of usage
