Over here in Serangoon, the PH of the water is lower, at 7.2 - 7.4.
Ever measured your tap water's pH?
I not sure if my block's tap water got problem or not... But using a calibrated pH test pen, I have a pH of 7.6!
I found this out when I happened to test my quarantine tank's water to see if it is similar to my main tank's water... And found that it has a pH of 7.8!
So what's yours? I trying to find out if it is just my block in Jurong East or somewhere else also have pH that high...

There can only be ONE
Hougang water fluctuates from 7 to 8 depending on time of day and how long you let the collected water settle.

brothers, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable--if anything is excellent or praiseworthy--think about such things.

Wondering what is added by PUB into our waters that made the pH so high?
I know acidic waters is due to acids... Then alkalic waters? Bicarbonate?
here in sembawang,PH is 7.0...
Ways to lower pH
· Filtering water over peat
· Add bogwood to the tank
· Inject carbon dioxide CO2
· Use a commercial acid buffer
· Water changes with softened water or RO (Reverse Osmosis) water
Alkalinity or temporary (carbonate) hardness (kH) refers to the hardness derived mainly from carbonate and bicarbonate ions and directly reflects the buffering capacity of the water. It can be precipitated and removed by boiling the water.
Permanent hardness measures ions such as nitrates, sulphates, and chlorides etc, and cannot be removed by boiling.
While there is a connection between water hardness and buffering, hardness is a product of mainly calcium and magnesium ions and buffering is produced by bicarbonate and carbonate ions.
pH of tap water is high due to lack of CO2 in the water. There are bicarbonates and carbonates (KH) in the tap water that cause the pH to be at around pH 8.
BTW clean water with KH of 2 will have a pH of 8.0 - 8.2 when CO2 is at equilibrium with atmosphere. Therefore, our tap water will KH range of 1 to 3, it is very normal for the pH to fall with the range of 7.8 to 8.5. I would even say pH 7.6 is on the low side for the tap water.

So in that case, in low tech tanks, pH will usually be high? And to reduce the pH, using peat and pH buffer is the usual way?
No. pH will reduce due to the bio activities.Originally Posted by valice
Why do you need to reduce the pH? There is no need to adjust the pH for planted tank.

The interesting thing I have is that I have a quarantine tank which is lightly planted and having a low low bioload currently...
After a quarantine period, my pH is about 7.8... So I definitely wouldn't be able to just take the fish out from the tank and put into my main tank which have a pH of 6.7... I try to equalise the two tanks by removing half of the water in the quarantine tank and then do a drip from the main tank in... Which is very very very slow and pH doesn't change as much...
So I was thinking whether is there any way to reduce the pH in the quarantine tank...
You will probably still need to do a proper aclimatisation when you transfer your fishes from one tank to the other whether the pH is the same or not. pH isn't going to be the one and only parameter that is different between the 2 tanks.
If your main tank is CO2 injected to reduce pH while your Q tank is buffered to reduce pH, the water will be drastically different even if you have the same pH.
