Quick update:

Will be putting about 25 tons into the pond week after next. Was wondering if I should be concerned about any of the other 'very low' elements from my water sample report. I don't know what SAR is on the report but if I need to make any other element adjustments for say, sulphur or one of the other elements, I think now may be the easiest and best time to put them in.

Once again, thanks to all for your input.

Warmest Regards,
Paul
