I was not doing top offs before now. I just noticed here in the last few days that the water level has been going down consistanly over the period of a few days

And it will continually do so more and more as time goes on. So be ready for it

Yeah my only concern is any residual bacteria or fungus residing in the cooler but I think I can just fill the coil with Physan-20 for a couple hours and it should kill anything in there.
MFGR says to run vinegar through it to clean scale, like a Keurig haha.
Dont sweat it! I lost out on a 1/10 chiller last month by not making up my mind and getting it fast enough. I literally have been trolling CL since then just waiting. I live in CO too so there tends to be a lot of grow stuff going up for sale. Just keep an eye out.
I gotta pick up some stuff for a fence and then I am going to pick her up.

As far as the plants, the PH dropped last night for the first time ever. It was at 5.8 and this morning it was 5.5. Water went down and nutes went up 10ppm.
It means something but I need to read about it. The plants are beast anyway. I am not seeing any signs of them being unhappy.

Getting to be like bushes in there haha sort of....

So here is the chiller. The guy had three of them. I guess he tests them for the company or something. Nearly New! I poured Physan-20 into the tank and am letting it sit overnight. This will help ensure that I harvest. 175
