Review: It’s saved my Java Ferns! - The seller that I purchased the bottle from was Sai Aqua World and they had sent me a genuine and original product. Yes there was some crusty residue around the cap but this isn’t due to a leak from the bottle. Any Seachem product you buy in India must contain the importers hologram & importers label (which has the date of import, importers email and phone number with a proper bar code). I’m very happy with my purchase and that it is an original from the seller that I purchased. This product itself is excellent, any planted tank needs an NPK (nitrogen, phosphorus, potassium) based substrate or fertiliser. Fish waste/poop provides the N & P that aquatic plants need. I have a lot of java fern in my tank whose leaves were blackening due to a lack of K which I was able to dose with this. My plants are thriving now! Thank you so much!
