Calculating Ratios

[diverrk]

Ok call me Math retarded, but I am trying to figure out how to calculate a ratio. For instance 5 grams ( 1 teaspoon) to 40 gal How would I calculate for 1 gallon . I am considering usin Seachem Buffer to help with PH level

 

Thanks

Divide by forty

 

.125 grams per gallon

For one gallon it would be 5/40, or 1/8 of a gram.

[herranton]

For one gallon it would be 5/40, or 1/8 of a teaspoon.

Check your math

Herranton is correct on the measurment

[lakshwadeep]

Think of it like this ratio:

 

5 grams

40 gallons

 

to get one gallon on the denominator, you would divide by forty, so you divide by forty for the entire fraction:

 

5 grams ÷40

40 gallons ÷40

 

Which will be 5/40ths of a gram for one gallon

.125 is 1/8

 

You are correct, BUT It is one teaspoon. The answer is .125 Grams, teaspoons would be too much

You're right, I forgot that one teaspoon is 5 grams, so it would have been 1/40th of a teaspoon.

Sorry, I've edited my post to the correct answers.

I didn't mean to argue, just wanted to make sure that this guy didn't add too much too his tank.

That's why I edited my first post. I realized the minor mistake.

Don't worry, I was getting a little argumentative when trying to point out that .125 is 1/8

 

Anyway, diverrk: Why do you think you'll need a pH buffer? How low is your pH?

[diverrk]

Well right now I'm waiting for a test kit I ordered, but I used test strips that I have (for Salt Water) and it's reading around 7.5

 

Thanks for all your replies !

[lakshwadeep]

That's good you're getting a test kit. Test strips can be less accurate/reliable. Also, remember that pH can drop to low levels during the night (I've heard 7.9), so you may want to test at different times in the day.
