Green bottles for green fingers

Now that LED lighting has become a feature of the vast majority of aquariums, it’s time to test fertiliser compositions and perhaps re-adjust dosages, suggests JBL.
 
A spokesman for German aquatics manufacturer JBL said: “A higher light intensity means that plants need more nutrients (which they receive from the fertilisers) to grow faster. Otherwise plant growth would be stunted by nutrient deficiency.
 
“The JBL research department has reviewed the aquarium plant growth of 36 different aquarium plants under the new JBL full-spectrum LEDs, which have a photosynthetically-active radiation level of over 200 PAR, in relation to the compositions and dosages of JBL aquarium fertilisers.”
 
The JBL daily fertiliser needs to be administered every 24 hour, the JBL basic fertiliser Ferropol every seven days, the root fertiliser JBL Ferropol Root every 30 days, and the substrate fertiliser JBL AquaBasis and the fertiliser balls every 180 days. 
 
The spokesman added: “This simple but professional fertiliser system is guaranteed to work even with the most demanding aquarium plants.”
