I would do a 50% water change to bring down the phosphate levels and then add KNO3 (Stump Remover) to bring up your Nitrate levels to balance the Phosphate levels. They should be in a 10:1 proportion (NO3 : PO4). I keep NO3 at 7ppm and PO4 at 0.7ppm.
Also, as Rex suggested, make sure you are adding potassium and trace elements to take care of the plants "misc. needs".
Also, as Nordic suggested, turn those spray bars downwards to help eliminate some of that surface agitation. It is causing the CO2 gas you're working so hard to inject to simply evaporate into the atmosphere. Be careful, though, with fairly soft water (3dGH) the pH may drop fairly quickly once that CO2 dissolves into the water so keep an eye on it.
