Ph Levels

[usaboston54]

What are pH levels? can you please give me a basic overveiw with simple words? sorry i must sound so weird im only 11.

pH is basically a scale for how acidic or alkali the water is. It goes from 1 to 14

1 is very Acidic, 7 is Neutral, 14 is very Alkali

Different fish live in different pH conditions dependant on their location, some prefer more acidic, some prefer more alkali. When testing the tank water you should always test for the pH level, as if it is too high or too low it can stress the fish and weaken them, which may cause them to die, so it is important

Hope this is some help, (if it was too simple or not simple enough... Sorry, lol)
(Btw, you'll learn more about this at school and in more depth )

Here's a little graphic that may help;

Each 1.0 change represents a 100 times change in acidity or alkilinity, each 0.1 represents a 10 times change.

Show off
Lol

Each 1.0 change represents a 100 times change in acidity or alkilinity, each 0.1 represents a 10 times change.

Each 1.0 change in pH unit represents a 10 times change, not 100.

pH stands for negative of the base 10 log of the concentration of H ions.

That is, a pH of 7.0 = a concentration of 10^-7 ions, pH 6.0 = 10^-6.

10^-7 * 10 = 10^-6 ... only a 10 fold change, NOT 100.

You're right, that's what I get for posting while talking & reading a menu from the local bbq joint. My bad.

@Bignose, LOL: I think you've just lost the 11 year old!

Post again in about 5 years time & he might just get the jist of it!

 

[Tolak]

11 year old? He lost me after the first sentence!

 

[Underwurlde]

LOL, why do you think I posted!

Ok wise guy , you and your fancy log 10 base crazy. if you take the reading of your tank and graph them over the course of the month, whats the area under the curve? Remember yah have to use calculus on that bad boy.

Sorry usaboston54, just ignore the crazy talk..lol . the First and second post andwer your question.

 

[Underwurlde]

Quick everyone, hide in your bunkers, Bignose has just been challenged.

@Lord Zogat, it was good knowing you btw. Farewell!

Well,

the area under the curve should be a rectangle since the pH levels should be constant, no calculus needed for that. I also have no idea what the units of pH*days would mean.

I've noticed Bignose gets very specific when it suits him and also very generic when that suits him. Technically speaking, which Bignose is famous for, Ph is not a constant and would produce a curve if accurately graphed over a month's time.

 

[Bignose]

No, your goal is to keep a constant pH, if you are doing everything right. Specifically, doing your weekly water changes.

The fish will suffer if the pH fluctuates, so the goal is to keep it constant. No test for our aquariums will be able to accurately measure the tiny changes that do occur all the time, but over a month's time the pH should be constant.

Notice Bullrock, I said 'should' be a constant, and if you are trying to keep healthy fish, it should be.

 

[Underwurlde]

The integration of a graph, that is to say the accumated area of the area beneath a graph does NOT necessarily mean that it represents something just because it exisits (the result of the accumulated area that is).

For fluctuations of pH, delta pH, adding up the area under its graph, when plotting fluctuations thereof with regards to delta time would produce a meaningless result I believe.

Unless someone can educate me otherwise then (we) will learn something new!
