Seachem Safe Measuring Spoons - 5 to 125 Gallons

thingiverse

Used a customizer to create these measuring spoons for Seachem Safe Aquarium Water Conditioner. The instructions for Seachem Safe specify 1/4 teaspoon per 300 gallons. To give an example, this translates roughly to 0.033 teaspoons for 40 gallons. I rounded up to .04 teaspoons for a couple of reasons: first, to account for variation in printing, and second, to make them even numbers that are easier to work with. For smaller aquariums, the amounts are similarly calculated: 5 gallons is equivalent to .005 teaspoons, 10 gallons to .01 teaspoons, 15 gallons to .015 teaspoons, 20 gallons to .02 teaspoons, and so on. I then imported these designs into Tinkercad to edit them a bit and resize the handles. I now have measuring spoons for aquariums sized from 5 gallons to 125 gallons in 5-gallon increments.
