So I got my TF100 about a week ago and I've been trying to get all my chemistry into the recommended range for a SWG. Here are tonight's results:
I'm in the process of dissolving the 2nd half of my CYA in a tube sock in my skimmer, it's almost gone. I leave it in there even when the pump isn't running - is that okay? I've read a lot of conflicting views here about that. Once I get my CYA up to about 70, I'm going to adjust my SWG, I don't think I need as much run time. I'm shooting for a FC level of 5ppm.
My pH seems to be holding steady (I think). Over the last couple of days it's been around 7.5. When I first got my test kit I had to add MA to bring it down from 8.2. I ended up lowering my TA as well from about 110 to 100. If my pH holds steady, do I need to worry about bringing my TA down even further? Or should I just be happy where I am and not mess with it? I've been doing a lot of reading and I don't want my pH to drift or to put any unnecessary strain on my SWG cell. I just don't like adding MA, I'm terrified of it!!
Other than that, the water looks great. I'm in the northeast and we're getting a lot of rain from Hermine right now - does the rain raise or lower the pH?
Thanks in advance!!!
