You’ve cared for your fish tank and it has blossomed in to a beautiful marine exhibit. You’ve added fish, plants and decorations to your aquarium over the years, but how do you know when it’s time to upgrade to a bigger tank? Read on for a few guidelines…
Having problems with water quality?
Has it been hard to maintain safe levels of pH, ammonia, nitrates and nitrites? If so, a larger tank may help. Water quality and temperature are easier to maintain in larger tanks. These levels don’t spike as quickly in tanks with more water volume.
Are there too many fish in your tank? And how many is too many? The rule most often used is one inch of fish for every gallon of water, but this doesn’t provide enough room for larger fish and full-bodied fish, like goldfish. If you have larger fish or if they’ve grown, you may want to adapt that rule to one inch of fish for every two or three gallons of water. Also, smaller fish tend to be more active and may be happier with more room as well.
Want to include live plants?
Live plants provide a natural habitat for fish, but like any live addition to your tank, they will affect water chemistry. While they can help inhibit algae and offer benefits, they can also cause waste from decayed plant matter. For a healthy, vibrant ecosystem with live plants, a bigger aquarium is recommended.
