Hydroguard Water Appearance

I am just curious about those that use hydroguard as their only beneficial organism additive.

Does your water turn cloudy a few days after adding it to your reservoir?

No it shouldn't or doesn't. But some hydro stores still carry expired hydroguard. If you look close enough on the bottle, it's like imprinted an expiration date on there.

Ok, I wonder what is going on then.

so, if your hydro guard is not expired, what's the pH? when there are bad stuff in there, pH will drop like from 5.7 to 4.7 over night!!
