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
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.
