I stopped adding fertiliser during a Cyanobacteria outbreak, should I start adding them again?

I have finally got on top of my slime algae problem in one of my tanks. It is now heavily planted with hygrophila difformis, hygrophila polysperma, limnophila, frogbit, red tiger lotus and Brazilian pennywort. I have been using clay root tabs and nothing else. Will a liquid fertiliser upset the balance and cause another Cyanobacteria outbreak? It is under control but not eradicated. Thanks
 
Let your floating plants guide you. The rooted plants don't need any additional supplements. If the floating plants are growing and healthy then the answer is no. If they are struggling you may want to give them a little help. If you do start off at half of the recommended dosage and only adjust after a few weeks if there is no improvement (and no more cyano).
 
I concur with seangee.
 
Thankyou @seangee i will try this, my frogbit is definitely looking a bit stunted at the moment
