You have to be careful when buying ferts from garden centres as most contain urea or ammonia/ammonium as the source of N, which would cause an almighty algae outbreak in the tank!

If you have time, this is a great source for dry ferts at a very cheap price, I'm using these at the moment, 2kg of N and P will last me years!

Traces are OK but they may not be chelated, which is an expression meaning the holding the nutrient for a longer time to give the plant an opportunity to use it. This is not that big of a deal though as you can just add it more frequently.

Trace Element mixes are quite rare in garden centres. As Them says most are complete mixes including NPK which can contain urea/ammonium.

Also as Ceg says some use unchelated traces if not mixing into a ready made liquid solution.
