ok added the water and rechecked everything. only thing that changed was the TA and Ph. ph has been around 7.5 or 7.6. a little low at 7.2 and ta has been at 120 and now 130. It says to lower TA u have to lower ph to 7.2 and aerate. Well it did that part for me on the ph so i didnt add anything to raise ph. I aimed return nozzle to the top of the water to try to aerate, and will have the kids splash tomorrow. how long should it take to get TA down?
