Are you testing your water yourself? How's your levels looking?
So I'm in the same boat and my start up guy is no extra cost, because I'm so cheap I'm going to let him pay for the first month of chemicals especially since new plaster requires a lot of acid lol
However , I have been going behind him and testing daily with my tf100 test kit to make sure my numbers are in line. I'm going to be buying some chemicals so if something is not right I will just add what's needed. Plus they pay for all the salt after 30 days which will save me a little change that way I can buy a new pair of running shoes Hahahaha
