Ive been looking around my town and online to where I can purchase these fertilizers. LPS and Gardens does not carry dry ferts. This is the only site online that sells them in small amounts and with very reasonable shipping plus the fact that it only took a week to ship from CA to CT proves that this is the best place to get our aquarium ferts. Ill go straight to this site whenever I would need to restock my ferts.
WHAT ARE THE BEST LIQUID FERTILIZERS FOR THE AQUARIUM
The best fertilizer depends on the number of plants that you have. Fast growing, delicate plants quickly use nutrients from the water and substrate, so need a higher level than more hardy species.
If you have fish remove uneaten food after a few minutes as this can promote algae growth which depletes nutrients from the water. Whilst plants do require a low level of nitrates and phosphates, even a slightly raised level can boost algae formation.
For more advice and information speak to your local aquarium specialist.

Most missing nutrients are micro-nutrients or trace elements. These are all mineral, and include iron, copper, manganese, zinc, etc. Good liquid fertilizers contain these elements. Seachem's Flourish Comprehensive Supplement for the Planted Aquarium is one of the best, Kent's Freshwater Plant [not sure this is still available, haven't been able to find it for some time now] works (I used this in the 1990's), and I believe from the info on their website that Nutrafin's Plant-Gro is comparable, though I have not myself tried this. I currently use the Flourish.

That’s where we come in. We manufacture Yamato Green Aquarium Plant Fertilizer, and we happen to feel that it is the very best fertilizer in the world. It contains all the nutrients your plants need, in the correct proportions to meet the plant’s needs. Many fertilizers seem to just dump in a few ingredients and call it a day. But Yamato Green fertilizers are a very complete formula, containing all the nutrients required by your plants, in exactly the correct proportions to meet the needs and demands of your aquarium plants. Plants need nutrients to grow. CO2 is the most important of these, but the others must be added also. If you feed your fish a lot, then this may supply all of what the plants need. Some people have beautiful plant tanks with no fertilizer other than digested fish food. The unfortunate thing about fertilizing this way is that all these nutrients are available to the algae as well. If all this digested food could be kept deep in the substrate, the plants would have a much easier time getting at it than the algae. For this reason I prefer to feed my fish VERY sparingly and to use a solid fertilizer in the substrate. I have used brand pond lily tablets with great success (after having tried many made-for-aquarium additives which weren’t as good and are generally overpriced). I break the rather large tablets into 8 or 16 smaller pieces (best accomplished by placing a flat-head screwdriver onto the tablet and striking with a hammer) and push them deep into the loam/vermiculite part of the substrate. This helps keep the nutrients out of the water and near the roots. I would use no more than one whole tablet per 20 gallons water when you first plant the tank, and then add some weekly until the nitrate levels in the tank rise above 5 ppm (see algae and test kit sections). At this point there is probably quite a supply of fertilizer down there and you can stop adding it for awhile. Note that I assume you are feeding sparingly enough so that the food alone would not cause any readable nitrate levels.
