Try this volume calculation: 0.45 x (A+B) x length x average depth x 7.5 volume (in gallons) 0.45 x 18 ft x 25 ft x 5 ft x 7.5 7593.75 gallons Parts Per Million (ppm) One of the most important calculations you will use is parts per million (ppm). Small tanks tend to require a much lower effort but more frequently. all have to be increased in size and/or number to properly address the larger physical dimensions and increased water volume.Īnother consideration is the frequency and amount of effort required when maintaining tanks of different sizes. This page is designed to approximate the water volume for different aquarium. Pumps, skimmers, heaters, powerheads, sumps, etc. Chemistry Calculator Version 1.04 Best Viewed at 1024 x 768 resolution. Lights aren’t the only thing that increases with aquarium size. I have a 180-gallon aquarium on the way to replace the 120 and I won’t need to purchase any more lights, fortunately.

For instance, my previous 40-gallon Red Sea aquarium required a single light. For example, to convert from liters to gallons you would multiply by 0.001 then divide by 0.003785412. Calculating the volume of a cylinder in gallons can be done using this formula: V.
