I agree with the dry fertilizers. I use them on all my tanks from high tech to low tech. They are far far cheaper then anything else. You can make a 500ml bottle of flourish for less then a dollar using dry fertilizers. Mixing dry fertilizers is very easy and even if you overdose you will not screw up your tank or harm your fish.
I also dry dose cuz like the rest of you I am lazy;-).
