Tank Placement.

So you think you've figured out what sized tank you're going to need. Awesome! As per the old saying "measure twice, cut once", let's make sure that this good decision can turn into a great one.

Ask yourself the following questions:

Is my tank going to be a near a window? 
If so, you may be inviting an algae growth issue in the future. Extended exposure to light creates an excellent atmosphere for algae growth on your tank walls, your substrate and the decorations as well! Adding an algae eating specimen to the tank may not be enough to keep it at bay.

Another concern with placement near a window can be changes to the temperature. If the sun is beating down on your water all day, you may cause the fish extreme discomfort resulting in stress and/or death.

Is the tank going to be on a flat surface?
This may sound silly, but some tanks can be under a lot of stress from the weight of its contents. Providing a level and supportive structure for it to rest on can help reduce the chances of the tank acquiring pressure cracks  or even outright breaking. A leaking tank is not something most people want to deal with!

Where is my tank in relation to maintenance items?
Carrying buckets full of water up and down stairs is not the most enjoyable experience. If the bucket is too full - a likely scenario if full buckets mean fewer trips up and down the stairs - splashes of water can end up in places you don't want them to be! This point is particularly important in my experience because it has an impact on how willing you become to perform necessary water changes. Even if the tank is not up/down stairs, a "long" distance away from a water source can be a nuisance.

There are some alternative to the traditional manual bucket-and-syphon system. If you place your aquariums appropriately, there are products on the market that can syphon directly out of your tank and straight into your sink. To make the deal all the sweeter, they can pump tap water straight into your tank as well. You can find products like this Aqueon Aquarium Water Changer - 25 Feet on Amazon for a fair price. From experience, it took roughly 25 trips to the tap to fill my 75 gallon tank for the first time!
