Low pH... a bad thing?

After switching over to using my local Chicago tap water from RO/DI I found that my pH had risen to a more acceptable level. This was a good thing as it was in the low 5's!!! Now it seems that for my CO2 to kick on and get good saturation, the pH ends up 5.9-6.2. Is this too low? Will this cause any problems? The fish and plants seem fine... I am sorry but I don't have a GH reading right now (if this is even a factor).

WHAT! I'm in the southwest burbs (plainfield) and my pH is in the 8's . No fair! As long as you keep fish who like acidic water that definitely won't be a problem for them. It only becomes a problem if it drops below 4.5.

I may have to find a public washroom where you are and steal water from their tap. muahaha.

I'm pretty sure the ADA Amazonia II soil is the main contributing factor to my low pH.... It's probably 7.2 out of the tap.

It is said that ADA Aquasoil original and II work so well at growing plants because they are both nutient dense and they change water parameters(GH, KH, PH) over time time to favor plant growth. I doubt that a drop in a PH as long as it is not a drastic drop over a short period of time would be bad for plants and fish. Most aquatic plants prefer lower pH levels but can tolerate a a wide range of PH levels. For fish a consistent ph over time is more important and IME, a raplidly fluctuating(up or down) PH over a short period of time can be lethal, with the exception of PH drop(s) caused by C02 injection.

If your concern is healthy algae free plant growth, then you need to focus more on appropriate light and c02 levels than PH, GH, KH, etc, etc.,

Would the lower range pH affect CPD's? Or if the pH always stays in the same range, I could just acclimate them very slowly to my water?

Does ADA aquasoil REALLY leach ammonia into the water... ?

WOW!!!
