Although swords may seem to be heavy root feeders, they are also heavy leaf feeders also. Basically, they are just plain nutrient hogs. Root tabs alone will NOT do enough for the plant.
Liquid fertilizers are best for smaller tanks, 55g and smaller. Pfertz products are awesome. They have just released a more concentrated formula that really makes in nice and a much better buy. Any tank larger than 55g, 70g and above, Liquid fertilizers become not very cost effective.
Fertilization, the feeding of your plants, should be balanced. The trace elements are just as important as the major elements NPK, nitrogen, phosphorous and potassium. All need to be dosed in the proper amounts.
Good soil is also key. Personally, I like using EcoComplete for Planted Tanks. I do have tanks using a blend of gravel and Fluorite, but do not like this combination as well.
I use API root tabs. The bottles I use are a better buy than Seachem. Seachem sells their product for a $1 a tab and, to me, that is NOT a good buy. I also use Jungle tabs in my larger tanks. These are normally for pond plants but I have used them with great effectiveness.
