Thread readers' FYI: Here's the Sera Master Freshwater test kit on Amazon: http://www.amazon.com/Sera-Aqua-Test-Freshwater-Master-Test/dp/B003XJAZDW/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1358628262&sr=1-1&keywords=sera+test+kit ... and the API for comparison: http://www.amazon.com/API-Freshwater-Master-Test-Kit/dp/B000255NCI/ref=sr_1_1?s=pet-supplies&ie=UTF8&qid=1358628438&sr=1-1&keywords=api+freshwater+master+test+kit.

There is quite a difference in test kits. The Sera Master kit tests for pH, kH, GH, NH3/NH4, NO2, NO3, PO4, Fe, Cl. Sera also includes online analysis of your water sample. The API Master kit tests for pH, NH3/NH4, NO2, high range pH, and NO3.

I have the result of the outside tap water. In order to compare apples to apples, I used the same test method before. Note: Outside tap water is much colder, impacting pH.

GH: 180 ppm
KH: 40 ppm
pH: 7.5
Nitrite: 3 ppm
Nitrate: 40 ppm
NH3/NH4: 0.25 ppm

For comparison, here are the inside tap reading from my earlier post:
I must say I am not sure what to suggest here. The GH at 180PPM [= 10 dGH] could be dealt with by diluting with RO, and this would be much better than using the softener water. But the nitrite and nitrate are high. The ammonia is much less of a concern.

Cold shouldn't affect pH, this is more likely CO2. Shake the water very briskly for a couple minutes to outgas the CO2.

I have to take my neighbour's dog out for a walk now...I will come back to this and in the meantime others may have suggestions.

Water ionizes further as temperature rises. Therefore, hydrogen ion concentration rises with temperature. Electronic pH meters always have a temperature compensating probe.

Have a good walk - Our three dogs (two Cairns and a Westie) have their own outside adventure, complete with 3000g Koi pond and 25' stream. We do take them for walks and the dog park for socialization's sake. TTYL when you're back.

Thread reader's FYI: For an excellent treatment of pH read Temperature and pH Measurement. The temperature effect on pH is not direct. You can see it relationship in the calculus regarding ion equilibrium; hence, the inclusion of a temperature senor in electronic pH probes.

My apologies if I added to any confusion that already exists.

eHow has a much more friendly description of pH (read The Effects of Temperature on the pH of Water | eHow.com). For our discussion here - using test strips OR reagents, temperature is moot.

Can anyone address this earlier question (or is it addressed in the other comments regarding water quality)? I am concerned that anaerobic bacteria could be kicked up during the cleaning process.

I myself would not worry about this. You can vacuum just a part of the substrate at each water change until it is all done. Areas around plant roots can be left alone, if any of the plants in the substrate are still alive.

The initial issue was sudden death of fish (and plants, but we I think have dealt with the plant issue). Frequent water changes, not doing too much at each, should get this back to normal. I am still concerned with what the water softener is adding, and this may have been the initial issue or part of it.

Anaerobic bacteria poisoning is usually associated with a sulfur (rotten egg) smell, cloudy water, or gasping at the surface.

Thanks to all for their input. The fish and plant are recuperating and appear to be in much less stress since taking the suggested steps regarding conditioning and water source. I will begin minor changes with treated outside tap water within the next four days.

I invite all to view my picture albums at http://www.tropicalfishkeeping.com/members/46916/album/. For me, success is always proceeded by a series of mistakes - some big, some small. I reckon that is what wisdom and the Grace of God is all about.

IMHO not always but I do tend to get it right the second time.

I learned a long time ago that usually the first thing I should look at is the last thing I did.

glad it's working

maintain Fw and marine system with a strong emphasis on balanced, stabilized system that as much as possible are self substaning.

have maintained FW systems for up to 9 years with descendants from original fish and marine aquariums for up to 8 years.

With no water changes, untreated tap water, inexpensive lighting by first starting the tank with live plants (FW) or macro algae( marine)
