KH + Ca 1 2 & 3

[Bradden]

I see there is a Grotech product as above.

I'm a bit confused. I think that KH +Ca1 increases Carbonate hardness, KH + Ca2 increases calcium, but what does KH + Ca3 do?

Also can you tell me do these products also contian trace elements eg magnesium strontium etc?

Thanks

The third one is for re-mineralising RO water. You'll find details on their website (http://www.grotech.de/ENGLISH/index.php?c=1&s=khca1-2-3)

If you want to supplement trace elements you need their Corall A, B, C range which you'll also find on their site.
