I think the shorted mixing time was something to do with clarity , But I'm not putting water into my system that has a redox of near zero into my tank, As is I see the ORP drop doing water changes. So if their new and I mean in the last year , has done something to require instant mixing and using I'll go elsewhere.
Makes NO sense to me as to why the CA would drop from extra mixing ? I got 2 buckets ( both broken too as they have gotten cheaper) from 2 different sources, 1 from Dr Fosters the other from Red Sea direct and they both mix to 360 calcium ? Has anyone with no troubles actually checked their new batch for CA ? I was guilty of trusting red sea to deliver what they say, I know when I started using years ago I loved the 450-460 calcium I was getting getting.
But I was noticing my CA levels dropped after water changes so I checked a fresh batch and now I know why.
