I wouldn't jump on ESV as being your source of phosphates. I don't have any problems with phosphates with ESV's salt.Used ESV for the last year and recently switched to regular TM. It mixes the same every time for me and clears within 10 minutes or so.
I switched from ESV because it was testing positive for PO4 on a fresh mix. Speaking to the owner, he claimed this was within tolerance and acceptable. I didn't agree. I too sent in a test to Triton. I tested my tank water and not fresh mixed water. It showed very high levels for manganese and lithium. So I bought a few buckets of TM to see how things go. So far I like it. I may get a bucket of TMP to see what that's about. Both TM products are available from Petco at a discount with free shipping and can be placed on an automatic replenishment schedule to show up at the door without having to remember to order. ESV was becoming problematic, not being available when I needed it.
