Hardness,Calcium,Magnesium
I just read Charles's post, and I have similar questions. I think I will
limit mine to my tap water for now. The "Routine Tap Water Analysis" from I
obtainedmy local utility gies the following values in mg/l:
ph 7.48 K
3.6
alkalinity 23 Cl
1.9
conductivity 103.3 Na 5.4
T.D.S. 51.7 Flouride
.92
Total Hardness 40 Manganese
.009
Calcium Hardness 30 Zinc .01
Langelier -1.825 Lead ,15
below MCL (?)
pHS 9.305 Copper
,1300 below MCL
Ca 12 Sulfate
1
Mg .244 Chloride
100
Nitrates .6 Ammonia,Aluminum,TONS,Hydrogen
Sulfide 0
Orthophosphate .618 TNM's below
MCL
Iron .022 CO2
3.2
I think I understand enough to know why the pH of may 20g. dropped below 6
upon introduction of DIY CO2, but I do not understand the best method to
buffer ny pH at around 7. What else could you chemistry whizzes deduce from
the above which would help me develop my tapwater into great plant aquarium
water and reduce the chances of contracting algae plagues? Thanks for any
analsis, suggestions or encouragement. Ernie De Pascale
