Ok, so I started my 16 gal tank about a week ago. I used safe start, easy balance, and aqua start all by tetra. I got some live plants and a large log made of some kind of stone. Anyways, I've been testing the water almost every day now and I get my pH at 8.5 and alkalinity at 300 ppm. Now I dont have a super fance test kit just the one that uses the paper. How do I go about lowering this.
