Anyone set up an aquarium (medium-small) in their home recently? Any pointers / suggestions. Do's and Don'ts ?
Find a shady spot that doesn't promote algae growth. Maybe there's an aquarium glass out there to screen out the UV (or whatever wavelength) that promotes it.
50-gallon tanks are a lot heavier and need bigger stands. However their water parameters are more stable and less subject to rapid changes, giving you more time to respond in a crisis like a power outage.
If you're using an air pump then use two of them and consider putting acoustic insulation (like Acoustiblok) around them.
Make sure your fish get along with each other. We mainly stick to tetras & zebras. We've given up on angels.
Live plants are a pain. Plastic plants are quite realistic and require a lot less work.
Pick your spot carefully before you fill the tank with water. We had to move our aquarium about 20 feet for our familyroom renovation, and the project took most of the morning. The contingency planning resembled some of my submarine nuclear-maintenance projects... right down to the spill drills.
Rule #1 before changing the tank's water level: shut off the heater. I don't know how many times we've started changing out the tank's water only to realize that we've forgotten to shut off the heater, which promptly attempts to fry itself.
Spouse is an oceanographer who feels that keeping an aquarium is part of the job description and necessary for professional credibility. We've kept fish for most of the last 25 years, so I was surprised when she (spouse, not the fish) recently suggested that she was about done with the hobby. The lights & air pumps consume about 25 KWHr/month (over 7% of our total), so getting rid of that electrical load would mean that we'd be producing more electricity than we'd consume.
