The plants in my nano tank weren't growing or flourishing, and I had started to see pin holes in the older leaves, with some yellowing. I also had some cyanobacteria that seemed resistant to water changes, black outs and even chemical treatment. Researched, and decided to try potassium. What a difference! Plants started growing again. All new growth is lush green and vibrant. The cyano growth slowed by 90% and the whole tank feels happier and healthier. (I have also added some Limnophila Sessiliflora which has out-competed the cyano magnificently. Wish I had started with this wonderful plant) Anyway, all my tanks are now getting Seachem Potassium regularly (but not excessively), and all the many plants seem very happy about it.

Este es de los mejores abonos de potasio del mercado. El producto me llegó en perfectas condiciones y es imprescindible para todo acuarista que tenga plantas, ya que el potasio es uno de los macronutrientes necesarios para el correcto crecimiento de nuestras plantas.

Si tienes plantas es obligatorio añadir potasio K ya que esté no se genera como el nitrógeno N o el fósforo P y es el 3 macro NPK necesario en cantidades para muchos tipos de plantas, no es más que sulfato potásico diluido en % con agua destilada que a posteriori puedes calcular, mezclar y rellenar para reutilizar el bote

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!
