arches2 Posted October 17, 2012 Report Share Posted October 17, 2012 Start by reading the Nitros water maintenance stickie in this forum. Re-read it until you think you understand it. then read it a few more times. then get yourself a proper test kit. Trying to do this with strips is aggrivateing at best and nearly impossible at worst. You need to be able to do an acid / base demand to know how much is needed. You didn't say how you "brought the TA to 80" and what it and the pH were when you started. If it we me in your spot with the tools you have I'd add about 1/8 of a cup of baking soda to bring the TA up slightly and then just aerate (run the jets and air). that should get you close but until you can get exact numbers with a good test kit you'll be chasing it forever.
