Hey, recently I went to the LFS to get water tested and such. They said that I delayed my cycle when I did water changes. They told me to not do any more, and in 2/3 weeks, the water should be good. It's been 1.5 weeks since, and my ammonia is high still. They also said that my pH is very low, around 4.8 or so. What should I do? Continue water changes, or listen to them? Any advice guys.
