Help please! Cement in pond
In article ,
how wrote: wrote: yes. add muriatic as recommended by someone else on the list, dilute and drip it in gradually. yes, baking soda dissociates to CO2 and H2O in the presents of acid. Actually goldfish and koi do well in hard water, but lakes are naturally soft, they just arent "softened". soft water is stripped of any buffering capacity, Ca+ and Mg+. that means the pH will swing wildly and that makes the fish suffer. in addition softening strips out chloride ions which are necessary to gill function, breathing. and softening adds scads of Na+ which can sometimes be so high it is toxic. http://tinyurl.com/5fsbu9 snip Hi, The OP does not state any water parameters and muriatic may not be the cure. Use muriatic only if KH (alkalinity) is above 200ppm and pH is 9 or above. If KH is low and pH is 9 or above then baking soda will raise KH and lower pH. Keep adding baking soda (1/3lb per 1000 US gal)each day until KH reaches 150-200 ppm at which point pH should be about 8.4. OP's issue is probably moot now, if the problem was fish - killing bad then it's cured or they're dead. BTW never saw sodium thioglycolate used to neutralize chlorine, Chlorine forms pi bond with double bonded carbon? always used sodium thiosulphate. Chlorine forms pi bond with double bonded sulfur? Not chemist enough to say it won't work just never heard it being used.
