Should I Add More Ferts

[Kevstir]

Hi Guys

Iv been adding some tropica plant nutrition (not the +) for a month now at 10ml a week (plants doing fine apart from some black algae on the amazon swords) , just wondering if adding more during the week would benefit ?? if so what dosage should i try ??

here's a pic of the tank as it stands , lighting is 1 x 25w interpet triplus at the front and 2 x 25w arcadia freshwater tubes at the back , gives about 1.5wpg , don't have any c02 and have nutrafin grow sticks under the roots.

For a tank like this I would just use it at the Tropica recommendation contained in the instructions, dose 5ml per 50l water per week.
