You guys/gals must not have kids, or they don't get sick
I have three kids so it's very frequent that I have to use the cups or droppers that come with bottled children/infant over-the-counter medicines. Or just go to any pharmacy store and ask for a dropper; it's free btw. It has 1/8 of a tsp measurement intervals.
Yep, look at baking supplies for the more precise measuring spoons. As for the premixing I'm pretty sure someone has contacted seachem in the past and the official answer is that safe is not shelf stable premixed for more than a couple of days. It's pretty hard to overdose safe anyways, I use approx 1/2 tsp of it on my 110 with no negative effects so underfilling a 1/4 tsp should be fine for you.

Safe
Product Description
Safe™ is the complete and concentrated dry conditioner for both fresh and salt water. Safe™ removes chlorine, chloramine and ammonia. Safe™ converts ammonia into a safe, non-toxic form that is readily removed by the tank’s biofilter. Safe™ may be used during tank cycling to alleviate ammonia/nitrite toxicity. Safe™ detoxifies nitrite and nitrate, allowing the biofilter to more efficiently remove them. Safe™ is non-acidic and will not impact pH. Safe™ will not overactivate skimmers. Use at start-up and whenever adding or replacing water.
Sizes: 10 g, 50 g, 250 g, 1 kg, 4 kg
Why It's Different
Safe™ is the dry version of Prime® and shares all of it’s advantages; however, Safe™ is even more concentrated than Prime®.
Directions
Directions for 10 g and 50 g
To remove…
Chlorine: use 1 measure to each 130 L (35 gallons*) of tap water (removes 1 ppm)..![]()
Chloramine: use 1 measure to each 100 L (25 gallons*) of tap water (removes 1 ppm).![]()
Ammonia: use 1 measure to each 32 L (8 gallons*) of tap water (removes 1 ppm). Do not overdose! For reference, 1 measure = 100 mg. To detoxify nitrite/nitrate in an emergency situation use up to 5 measures to each 40 L (10 gallons). Use fish to gauge toxicity reduction as test kits will still show presence of nitrite/nitrate even when detoxified. May be added to aquarium directly, but is better if added to new water first. If adding directly to aquarium, base dose on aquarium volume. If temperature is > 30 C (86 F) cut dosing in half.![]()
havent searched but a member on another forum was selling safe powder from the ounces. he said an ounce of powder safe treats 3000 gallons.
I've always used the amount based on volume I'm replacing with no adverse effects. I have a pretty clean water supply too though, so that could have an effect. I usually only really eye mine because I'm also guessing on the volume of water I'm changing. It's always roughly 150 gallons or so. I'm sure I'm using a little bit more than maybe I should if I were to measure everything, but i doubt it would amount to more than a dollar or two a year, based on 500 gallons or so.
A kilo of safe treats 200,000 gallons and is about $30 online. Doing 50% water changes on my tanks would mean Id get 800 changes out of it or basically 15 years worth of water changes. So water conditioner costs me $2 a year.........if I eye it heavy I'll spend $3.
Just my 2c.
