It looks like you were right on Lenny. The pH was up to 7.8 at 6 pm last night. This morning it was 7.4. This was apparently due to the CO2 uptake of the algae during daylight hours resulting in increase pH.

None of the things you mentioned seem to apply in this case. The pH is always stable at 7.4 without any stabilizing agents. The aquarium gets a PWC every week with very good gravel cleaning. There are no live plants in the tank. It has very little algae. The canister filter was cleaned on Tuesday. […]
I always rinse the tube and cap with aquarium water before filling it for testing. Â Jimmy McHaney Husser, LA
This week I was out of town for three days over the holiday and decided to leave my fish without feed. When I returned home Saturday night all of the fish looked well and ate normally. I did a pH check on the water and it had gone from 7.4 (usual) to 7.9. This is in a […]
Ray, thanks for your informative post on the subject of my unfiltered water tests. It’s good to know that I have options. Currently I am only keeping fish, not breeding. I have 3 tanks, a 90 gal, 20L gal and 10 gal… I do weekly 25% PWC on the 90 and twice a week 25% PWC […]
50 lbs of limestone is added to the filter at each recharging. It last just over a year. I like to change it before it runs out completely so my water quality will not change for my PWC. I bypass the filter for water I use outside the home such as lawn water etc.  Jimmy […]
Thanks for the response, I tested the unfiltered water using an API Liquid test. The pH was 6.0 minus. It is the lowest on the color chart so I don’t know for sure how acid it is. The KH is less than 1, the GH is 2 dKH. I’ll test it again in 24 and 48 hours.

Thanks Lenny & Steve,  The house is about 15 years old. It has pvc pipe in all of the areas that I can seen which is most most if not all. I can bypass the filter, although it will all be cold water. I will do a pH, KH and GH test on the […]
A followup on recharging of filter on water well. First I was mistaken as to the kind of filter that was on my water well. Last year and in previous years when the well filter was recharged I was not keeping fish and did not pay that much attention to what was being done to the well. […]
