Yeup, checked with the shopkeeper, was told that it will spike. Said that the substrate adjusts the water so that the pH levels at below 7, at roughly 6.5 or so, ammonia level is spike but it is non-toxic at low pH. Something like that, but in the, she still advised that i best keep the betta out of there till i've got my plants, shrimps etc in there and let the tank cycle.
