# How much Prime conditioner do I use for a 5-gallon tank?

How much Prime conditioner do I use for a 5-gallon tank? I just bought some, I've been using a different kind of conditioner before so I'm unsure how much Prime I'm supposed to use for 5-gallons. Thanks!

If I did the math right, it's 2.5 cc's. A little extra won't hurt.

Thank you! Do you know how I would go about measuring that out?

Just use half a cap full.

1 mL of prime can condition 10 gallons of water. You can use the cap of the prime bottle to measure. Liquid up to the first thread is roughly 1 mL so use about half of that for you 5 gallon tank.

Or just use a syringe if you have one lol

From what I've read and asking this same question for dechlorinating very small amounts of water, roughly 2 drops of Prime treats 1 gallon of water. So, about 20 drops or so should take care of 10 gallons. (I like to add a couple extra just in case, unless you pour the bottle in you're not going to dangerously overdose)

The absolute easiest way to measure is with a syringe. mL and cc are the same thing. When I measure for my 75-gallon tank I actually use a cough medicine cup, it's got a 5, 10, 7.5 15 & 30ml measure right on it! You might have one floating around in your own cabinet.

As others have said, a syringe works well. (I also use one for filling the vials when testing my water.)

Edit: 20 drops of prime for 10G of water, not 10 for 10
