### ⭐⭐⭐⭐⭐ Essential fertilizer for the planted aquariums.
*by J***D on 18 March 2025*

Essential product for planted aquariums for sure, if you’re looking to have any success with this particular part of the hobby.

### ⭐⭐⭐⭐⭐ Briiliant product
*by A***R on 22 July 2023*

I have noticed that you buy the cheap big bottles but have to use triple the amount but with the seachem u only have to use a small amount so ends up lasting alot longer so trying to save some money in the long run you may aswell buy the dearer product and it's made a big difference in my full planted tank. Before u buy have a look at the liquid quantitys on the back before you decide
