Tropica specialised fertiliser vs VIMI

The good thing about ferts is we can adjust the dosage to our needs. Likewise with EI you may want to start at about 1/3 dose and see how your plants respond if they show signs of deficiency then up the dose. A good indicator with all in one ferts is to test nitrates and you will see if they are building up or not enough. This will allow you to adjust your weekly/daily dose. Its not a perfect method but its a good place to start.

Both are going to be pretty dilute solutions in comparison to what you would probably be adding to your tank if you were using dry salts or making up your own solutions, as in EI. I would just follow the manufacturer's directions to begin with and then adjust up or down as needed. For what it's worth, George Farmer uses Tropica Specialised and doses quite a bit above the recommended amount, if I recall correctly from his video, in his 120cm tank. Of course it's heavily planted, not Iwagumi as is yours.
