I can change the power head right when dosing drop but cant put in main tank, so that should help ?

Should help, yes

Are you mixing alk from Red Sea powder, or do you use the liquid product?

Just que liquide i buy the 5l

In that case that is very-very much. It’s 3 times more potent than the powder & also common bicarbonate. 1ml of that raises the Alk 0.1dKh in 100l (~26g). I’d say you would need around 30-40ml/day max. Maybe 15ml/day for a start with the frags.

edited the numbers

The Calcium solution is also very potent. A lot more (6-8x at least) than conventional CaCl2.

The issues above is why I switched to ESV and never looked back (even includes trace with the 2-part and both parts are dosed equally no matter what).

I agree mag is fine where it is (1350 being ideal IMO). Also agree with precipitation city being the cause. I was expecting a 5"+ clam in there...

So take out all precipitation and dose a 2 part esv should help. I can try this, and i should have less précipitation whit a 2 part ?

Definitely yes to the first part. Precipitation is usually caused (from what I've read, this is second hand) by a combination of overdosing (especially into areas of insufficient flow), combined with a 'seed' crystals that buffer that hasn't had time to dissolve into solution comes into contact with and precipitates out. I'm sure someone will give you a better, more technical explanation.

As for switching, you could do it with Red Sea's 2-part but like I said, I just like the overall simplicity ESV offers. Plus it's incredibly affordable, especially in the larger volumes/concentrates.

Esv is good stuff. I used it for 2.5 years in my nano and 6 months in my 120 which is now run by a calcium reactor. Am currently using it in my 45 frag tank until demand pics up but that will be awhile.

Right, it kinda sorta mimics a calcium reactor without the drop in pH or introduction of no3/po4 inherent in dissolving media is how I think of it

Ok all done got the evs 1and 2 clean all the sump tube etc so no more precipitation on glass and tube, i did a 60% water change during 24h. (Almost a restat if something was overdosing) So now my kh is 7.7 cal 380 mag 1320(After 24h) I will put parameter it in check whit the red sea (more concentrat) then use the evs to maintane, well let see if i will need dosing really lest or more normal dosing thanks for the help i will give you new.
