Hey guys. I dont have a kh or gh tester. Im wondering if anyone lives in surrey and knows what our kh and gh is so I can get an idea. Im planning to go and purchase a kh and gh tester. Im having trouble breeding discus and im trying to get an idea of what to buy. I dont know if i should be lowering or raising my kh and gh. I dont want to spend money on kh and gh buffers that i dont need and dont want to make 2 trips after ive tested.
