My 55gal has a Current NOVA 108W (I think it's 108W...I could be wrong) T5HO fixture on it. I am running actinics and 10K bulbs. My bulbs need to be replaced (I think that's why my swords aren't doing so well...when I first got the fixture, my swords were epic) and I will not be changing the setup. I currently have jungle val, swords, giant hairgrass, some sort of broadleaf crypt (looks like a sword does when it's grown emersed, with the big spade-like leaves), and java fern. My val does pretty well, but the rest of my plants are kind of suffering. After I replace my bulbs, what kind of ferts should I look into getting? I know swords are root feeders, so root tabs would be best for them...but what about the rest? I've never had an algae problem in this tank, even when I first got the fixture and it was relatively new (I think it was only a couple of months old when I bought it), but I've never dosed ferts or used CO2 on the tank.
