Unfortunately I have not seen any “sales” ever on this product.Might have to have a look at the blue. Never really looked into what they mixed up to. I run my ALk around 7.2 to 7.5, so a 10G WC wouldn't be that big of a deal. At $63.00(cheapest I'm seeing on the net right now. Does it go on sale occasionally like IO down to like $34 a box?) a 200G box it's still way more then IO, but it could be a viable option.
Not that I'm not happy with IO, but having to dump acid in every batch is another process I could do without.
It moves very fast and both colors always $69.99, CDN.
There was an issue with consistency reported, that’s why I check every second box....so far....butt on.....18 boxes..
I was on Red Sea Pro for 3 years, great salt no problems. Then I moved to a 180g, three times the size so “cost” became an issue.
In two years since the change, I have not noticed one single difference in growth and colour. Stoneys are consuming about 18ppm per day, same as Red Sea Pro.
For me, that’s $30 a case savings.
