My TA is 140
So I know I need to increase CH, which I am going to tomorrow. My FC is coming down from shocking and looking good. So now I have a bit high TA and low PH. I know the main thing to do here is aerate, but my question is do I need to lower TA to 90 or is this OK? Just adjust PH and see how it goes? I don't really have anything to aerate with right now, so I am wondering. Otherwise I guess I need to buy a fountain. What is the main downside of TS in this range of 140?
