I was wondering if anyone has used calcuim carbonate in their water.
I am the one that posted about the calcuim bentonite on july 28.
est.. about 9000 gal pond. Green pea water.
I have been adding a coup of BS in my water every day for 4 days.
My readings are Amonia 0
Nitrite 0
Nitrate 0
Total hardness still 10
Total alkalinity still 60
PH is still 6.5

Hubby said if I was trying to make the water hard I needed to use Calcuim
Carbonate. He can get some at work.
Anyone use this or have thoughts?
Also some guy he works with told him to tell me to buy a roll of barley
straw and throw it in my settlement chamber.
I didn't think this worked for green water, just the stringie algae.

Calcium Carbonate works well as a pH buffer. You could also safly
double or triple your Baking Soda dosage (three times as often not
three times as much in one dose). You will also want add some higher
plants to out compete the algea for the nitrogen, if you already have a
number of higher plants try adding a potasium fertilizer to encourage
them. Potasium is the only one of the three major plant nutrients that
wont ocur naturally in your pond and many plants are limited in their
growth because of this.
Potasium is found in Potash as part of fetilizers labeld as Muriate of
Potash, Sulfate of potash, 0-0-22 or 0-0-60.

I never had to bother with the barly straw thing and am still skeptical
as to how well it would work on the pea soup algea.
