My tapwater pH is 7.2. Still higher than my tank normally runs at, but less than what it has elevated to. That said, I will probably do another water change very soon, and this time use distilled water (or RO water if I can find someone that has some around here.) just to see if indeed my public water supply hasn't changed. As a further point, I suspect that something "extra" has been added to the water supply as we've had a lot of rain lately (western Oregon) and our water supply comes from a lake.
The Hagan CO2 thingies work inconsistently (I have two). That's what I get for trying to save money. That's the reason that I started adding the Excel, hoping to further enhance the amount of usable CO2 in the water, seeing how the DIY yeast conconctions never really raise the concentration more than 13 mg/l. To answer your question, yes, the Hagan things were recharged recently, so there is a somewhat adequate output of bubbles.
Nitrate levels are usually around 10 ppm. I thought that was safe. As for phosphate levels, that is actually lower than what I get out of my tap water.
Since both you and Wasserpet point at the CO2 levels, I'll go ahead and refill both bottles and see what effect that has and report back on that in the next day or two.
As I read back through this, I begin to question two things... My tap water probably isn't the best (inconsistent and has high additives). I've been resistant to buying an RO system because of cost, but it might be time to bite the bullet.
Second, the Hagan CO2 systems don't seem to be cutting it. Might be time to make an investment there too.
