Kh And Ph

[sjolliff]

Im doing a fishless cycle my levels are getting high and my ph has dropped to 6.4

i dont really want tp disturb my water by changing at all

can i add baking soda to raise the KH thus raisin the ph?

if so how much baking soda for a 125l tank

As long as the cycle is fishless, don't worry too much about how much to add. I would try a teaspoonful at first and see what it does for you. You may need a bit more but it is easier to put more in than it is to take some out.

i added 7 tspn to get from 6.2 to aroung 7.8
