KH/GH Levels

I found some pretty good links for KH/GH levels.

The "experts" might want to go thru these and tell us if they're worth a **** or not..

well, i don't consider myself an expert, per se, but i found a couple of things of note.

article 1. submitted to the world from a corporate website. strike one in my book, though i have no problem with AquaPharm as a company. made some generalizations that bothered me (MgCO3/CaCO3 as the only ' "ion pairs" ').

article 2. aimed at pond keepers. nothing wrong with the info that i saw, but definately intended for use in association with larger volumes of water.

article 3. corporate site with a few GLARING annoyances. Ammonia does not increase in toxicity as pH increases. (as they stated). the opposite is true. and ammonia itself doesn't get more toxic, the ammonia/ammonium exchange just moves toward ammonia as pH decreases. the corrisponding link about ammonia makes no mention of the hydrogen ion exchange.
the nitrifying bacteria comment below the ammonia comment bothers me because they make no attempt to clarify or support this statement (corporate website not subject to peer review).

articles 4,5. no complaints. i have #5 bookmarked actually. (well the whole site actually. i find it a good mix of science and laymans explaination).

just my 2 pennies

:cool:

actually, you've got it backwards and they are correct.

actually, they didn't say that at all. they simply indicated that Ca and Mg form "ion pairs" with negatively charged ions "like" bicarbonate, forming calcium bicarbonate and magnesium bicarbonate; Ca(HCO3)2 & Mg(HCO3)2.

thats what i get for sticking my neck out... chop.

yup, i was wrong on both counts. i got so used to converting pH into pOH, that i confused them in my head, i think.

[NH4+][OH-]
___________ = K
[NH3]

duh.

i still don't like the language,(re:ions), but you are correct, liv.

forgive me, i beg of you all. back to benign statements, i guess. (just kidding, i don't mind being called on errors.) i'll never forget the exact relationship now.

:cool:

edit: i was tempted to change my original post, but thought it better to leave for integrety's sake, and to keep liv's relevent...

hey, if i had a nickel for every time i mis-spoke, i'd be a rich man. we're all often tempted to read articles by 'corporate' america and work hard to find fault with them, despite the fact that they may have good information. ... no, really ... it happens. i'm serious. why just 6 years ago i read just such an article. ;-)
