hi bros

A few days back i just set up a 3ft planted tank with co2 injection at 3bps.The volume of water is abouit 150l & i tried to increase the kh .In total i added about 7 teaspoon of sodium bicarbonate & kh went up to about 2dkh.

But the next day,the kh went down again.Any bros have this encounter???

Please advise.Tks
