Disaster averted!

a good summary of how to change water parameters. http://www.chelon ia.org/Articles/waterchemistry.htm "Ways to increase gH Adding limestone to the aquarium (this will also increase kH which in tur n will increase pH) Adding calcium carbonate will raise gH and kH" To lower the pH use hydrochloric acid, aka muriatic acid at your hardware store. Mix the acid into water (not the other way around) to dilute and then use a g allon milk jug with a bare pin prick of a hole to drip drop by drop into the pond. slowly change the pH over a couple days. HOWEVER, it could be with no calcium/magnesium ions your pH is fragile an d will change quickly sorta like distilled water will. I have quite soft wate r since it comes out of Lake Michigan, just a bit of carbonate too. Need to put i n organic dolomitic limestone to bring up the hardness. However, limestone paver s can also be set in the pond to moderate the pH. They will dissolve as needed.

Luckily we are expecting several inches of rain this week which will help with alkalinity, currently 300ppm and pH currently 9.0. Any good ideas how to raise GH when KH is so high? Somewhere between zone 5 and 6 tucked along the shore of Lake Michigan on the council grounds of the Fox, Mascouten, Potawatomi, and Winnebago Thanks, Dr Solo, When we originally set up the pond, I used muriatic acid the break the alkalinity, drop the pH and adjust the hardness. I must clarify that these efforts were PRE-Fish. I corrected hardness, alkalinity, then pH, much the same as one would do for a swimming pool. It's been many years now and I don't recall how much acid was used, but I remember it was ALOT. Now, with the fish in the pond, I am not comfortable trying to break the alkalinity ( oh it would be so easy). Having done some research, I think my course of action will include reef grade calcium chloride and magnesium. I believe it will be soluble even in high KH/pH conditions. Next question: Will it affect salt levels? And do salt tests measure the sodium or the chloride? Will report back on progress... elizabeth, Baton Rouge |
