That first chart I posted in the post above is not that good, you want one with a range like this one instead of just recommended and not recommended: www.hoseflex.com.au/files/EJ%20Catalogue%203.47%20-%20CHEMICAL%20CHART%20-%20S%20TO%20T.pdf
The hoseflex link doesn't seem to be working. Can you check if it is correct please. I have been using the initial one you posted and am curious about the difference.
Awesome job! Surrounding pavers done as well? I keep saying I'm new and a sponge... lol how long for the project and how much chemical, approximately. I'm just trying to wrap my head around all of the great info I find on this board.
