hi ! from your website, i found "aqua +KH" can only use in fresh water.
can i use it in saltwater tank?
thx a lot!
they reply:
Hello, it´s recommended for freshwater. The tabs contain a substance called PVP. And this substance will caus an overflow of your skimmer, if you add too many tabs.

There are a lot of brand with KH additive in the market,Kent or TLF..etc.This product is used on "half salt" fish that come from Africa.that';s all I know.FYI

Hi nini,
You can to use Sodium Bicarbonate, it is safety and lower cost.

thx rayliang and kenkuo for your reply!!
why i wanna use it is b/c of it can dissolve slowly.
i have not got a dosing pump currently and add Sodium Bicarbonate or KH additive straightly after mix with RO water will fluctuate KH quickly.
can anyone kindly provide the KH tabs with other brands?
thx!!
