Adding Fuel to the Nitrate Debate: Why Water Changes DONT Reduce Nitrates

[Guinness]

The amount of waste in the tank multiflied by the percentage of water changed is the amount of waste left in the tank. I worked it out with actual #'s to make sure I got it right, and I did. I think we will just have to agree to disagree.

Only if the WC=50% because 1-50%=50%

Perhaps it'll help if I tell you that I am qualified to teach business at university.
I is ridiculous but I don't mind if you disagree.

Now the lightbulb turned on. Every time I did it in my head I used 50% ok makes sense.
But degrees don't impress me, I've met many idiots with great degrees.

Fact:

If you do a 50% change per week & your tap water is zero; then your levels will NEVER be higher than the sum of your 2 highest weeks of waste production.

Even if you miss a few weeks (or more), then start again then they will lower levels to the same level no more than the sum of your 2 highest weeks of waste production.



Thank you for your time.


If you are bored, then read on for examples. see how a WC can actually reduce levels in example #2.

Is that why you list your occupation as singer ?

No offense... just makin' fun at your expense

Now the lightbulb turned on. Every time I did it in my head I used 50% ok makes sense.
But degrees don't impress me, I've met many idiots with great degrees.

I was not trying to impress you. It was my last resort to make you think. I am not sure I'll bother explaining anything to you ever again.

 

[Guinness]

Those are the right numbers, I just can't seem to get them from the discus forum equasions.

i had a thermometer with a lot of degrees, does that mean it's really smart?

I was not trying to call you an idiot. I read my post and it came off wrong. Sorry for any confusion.

[shekes]

I was not trying to call you an idiot.

Neither do I.
And I am also not impressed by degrees. It appears that I still have to learn to spend my time on more perceptive and grateful audiences.

Rapair,

I know you want to be like me but I am not even flattered.
