Interesting thread. All sorts (salts ) of chemical stuff being
recomended. I started my pond in May '06, about 650 gals. I hoped to avoid the use of chemicals by good management and filtering. Heavy planting, which is now flourishing, to the point I need to prune stuff back to see the water, a dozen or so fish (4 of which were born in the pond) all thriving, and growing at a rapid rate, particularly two koi. Ph at about 8.5, nitrate/nitrite/ammonia all zero. No chemicals. Some string algea, but nothing to be bothered with. -- ßôyþëtë London, UK |

One source is http://catalog.miniscience.com/catal...s/Default.html Thanks, Nick. That will work great for determining the salinity! (note sarcasm) lol You're welcome, Gearge. Please note regarding the other suggestion of a hydrometer that a hydrometer is an instrument used for determining the specific gravity of liquids, without regard to the substance that varies it from 1.0000, whether battery acid, alcohol, sugar, salt, etc. (Note lack of sarcasm - I find yours rather disappointing) -- Nick. Support severely wounded and disabled Veterans and their families! Thank a Veteran and Support Our Troops. You are not forgotten. Thanks ! ! ! ~Semper Fi~ My point was that a Ph kit isn't going to tell you anything about the salinity of your water. A hydrometer will. George |

Could i use a pool ph test just to see if it shows the level??

Basically if you've got a test kit that measures to 8.2 and you get a measurement of 8.0, you can feel fairly confident that it is 8.0 (assuming the reagents are fresh). If the test kits top mark is 8.2 and you get a reading of 8.2 one can't be confident that 8.2 is the highest the water will test. Why I like Nutrafin/Hagen's Wide Range, it tests from 4.5 - 9.0. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |

Frank Exactly. Just because it is "fresh water" doesn't mean that it doesn't have dissolved solids and chlorides. In the U.S., the national secondary drinking water regulations allows up to 500 mg/l of total dissolved solids in drinking water, and up to 250 mg/l of chloride. If your drinking water contains chlorides AND TDSs close to the allowable limit, you will have a relatively high salinity (as freshwater goes), and that can affect your Ph. That was the reason I asked the question. George |

Gill I have been told the hydrometers just aren't sensitive enough to be able to measure the salinity of tap water or even our pond water. They are designed for testing water with salinity of around 3.5%. My pond water tests at around 0.03 or 0.04% by salinity meter without any salt additions. When treating for nitrites, the level desired is around 0.1% to 0.15% which is still a very low level compared to the design of the hydrometer. One of the bottled waters that we have bought for drinking is a product of reverse osmosis or distillation, per the bottle, with sodium chloride and calcium carbonate added for flavor. G |

I thought pH was a relationship between hydrogen ions. How does salt effect the relationship? Regards, Hal |

places near coastlines or big salt deposits often have salt water
intrusion into their ground water. even rain and snow off oceans contain a bit of trapped salts. by salts I mean NaCl rather than the salts of other compounds. If the salt concentration is too high, the water tastes lousy nobody will drink it. some places are so alkaline that the water is nearly undrinkable, and enough magnesium to give non residents diarrhea.

there are different meanings for "salt"
table salt is NaCl, wont affect pH NaHCO3 is the salt of bicarb and will affect pH. salts in the generic form means any Na, Li, Mg, etc combination with negative charged ions. There are even salts of DNA.

G You can measure the total dissolved solids of freshwater using a conductivity meter. Here is how to do it: http://tinyurl.com/rn55l Note: Total Dissolved Solids=TDS (mg/L) = EC (µS/cm at 25oC) x 0.6 where EC=Electrical conductivity. George |

I added some ph down salts and it bought the reading down to 7.8 now. I
think that was the problem "~ jan" wrote in message ... On Fri, 29 Jun 2007 19:04:03 CST, "Paul" wrote: Could i use a pool ph test just to see if it shows the level??
