For pruning and planting, I find that the best tools are a nice sharp pair of scissors made from stainless steel, a long pair a of tweezers, and a small pair of tweezers (the kind for removing splinters). The long tweezers are used for the majority of planting, and the small tweezers are used when planting a foreground carpet like HC or Glosso.
For scrubbing the glass, I find that a razor blade and a palm size square of polyfiber work well. The razor blade quickly removes any extra stubborn accumulation while the polyfiber will quickly and gently remove the rest.
For cleaning filters and short tubing I find that that same piece of polyfiber works well. In addition I use an inexpensive toothbrush and a small brush intended for cleaning the nipple of a baby bottle.
