@irie ivan, thanks for the replies Sir Ivan. But can you correct my statement on the first part your reply? will a system run at 8.1-8.3 with a reactor going full steam for SPS growth and no kalk?
That is a very sensible statement about the metal's behaviour. You are 100% correct and it's that's an important behaviour of kalk I will now remember!
But.....I got curious.....is Brightwell selling somthing ridiculous?....or snake powder?
It turns out Brightwell say what chemicals they put in most products on the website, not specifics such as hydrous/anhydrous but go look. 'technical button' and look at ingredients.
So I got extremely curious and needed to know what they suggest 'kalk+2' is made from, so it's; Calcium hydroxide, Strontium hydroxide, Magnesium hydroxide.
Calcium (min) 54.20% (542,000 ppm), Strontium (min) 1.00% (10,000 ppm), Magnesium (min) 0.15% (1,500 ppm).
Notice how the Mg is 0.15% as opposed to the Sr of 1.00%. possibly to do with hydrous/anhydrous etc?
But more importantly, does it sound like it could work?
@irie ivan and
@carlosdeandrade ?Strontium isn't something to mess around with and never used hydroxides of Mg or Sr.
I don't like Brightwell , they sell Lugol's for around R475 for 125ml. I buy medical grade lugols at pharmacist at R200 for 500ml and the same goes for several of their other 'products'.
They are an awesome resource to 'poach' D.I.Y chemical additive ideas though, holy moly!! already scheming about the amino acids......
