I'm very suspicious that the pH 7.0 stabilizer block I added to my tank a few days ago is causing a haze I now have in the water. Its been fully cycled for several months and water was crystal clear until then. Anyone know this to be true or have a similar experience?
Due to the small size (6g) and the high pH of my tap water (~8.0) I'm having problems keeping the pH stable. When I checked it on Tue it had dropped to around 6.6 so I added the tablet to gradually increase back to 7.0 and maintain that level.
Since the actual tank capacity is around 5g, changing 1g of water each week with un-normalized tap water would cause a huge pH swing, certainly more than a 0.2 shift. So how to keep the pH stable without using "pH down" which just eats all my buffers and essentially destabilizes the water from the start?
I just don't understand how to retain buffering capacity and lower the pH, they seem mutually exclusive?
