Response to Plexi and film chemistry

One should not use the slot processor as a place to mix chemical... Even if it is not acetic acid. I did it without knowing, trying to dilute developer concentrate in the slot. I found it VERY difficult to agitate to make uniform working solution, and it took a while of detective work. I threw away a tankful of chemical to mix a fresh one out of raw chemicals just to realize the chemicals dumped to the sink was perfectly fine though it was not working at all in the slot when tested with small test strip.) By the way, it is best to chose formulae that have large processing capacity for use in slot processors because changing solution is cumbersome. I use BUFFERED stop bath because unbuffered acetic acid stop bath is way too acidic at the beginning yet its capacity isn't as large as mildly buffered version.
