Do we have any actual figures for cost of applying Alum compared with Phoslock?

you have suggested in your post here cost must be the limiting factor, but “what” cost?

Is Phoslock marginally, moderately or significantly more expensive to apply?

If marginal to even moderate thats exciting for us ( for if truly a superior product the US will look to swap, or as Phoslock grows they may be able to reduce price to compete) , but if significant, then it concerns me that maybe China may eventually turn to Alum if the cost of Phoslock is too much as they ramp up lake treatment.

Do we have any facts and figures at all re this cost comparison?

Cheers.
