Here's something I just cant figure out.
I've tried both Instant Ocean (not Reef Crystals) as well as Fritz RPM and in the container I mix these salts which is a 160 gallon Ace Roto-Mold storage tank made from polyethylene, the alkalinity comes in around 6.5 to 6.8 with a salinity of 1.025. I make a batch once a month when reservoir is empty and these results are pretty consistent. The water I use to mix with the salts is RO produced from my AquaFX unit.
Any thoughts on why this may happen? Could it be residue left from the previous month mix affecting the new batch alkalinity reading? Its quite frustrating because it takes me days to get it in line with where I want it to be, around 8.3.
Any help would be much appreciated.
