Hmmm so my 15 gallon tank has deff changed with the fluval Stratum.
This is my 29 gallon and its what my 15 gallon used to be before I switched to fluval Stratum.

I noticed the KH is gone, I have no idea what it is, should I be concerned with its absence? I plan on this being a heavily planted shrimp/betta tank.

Fluval Stratum is a buffering substrate. It's supposed to strip KH and lower pH.

Ah ok. I knew it changed ph but I didn't know it effected KH so I was a little worried, haha. Glad to know its normal.

KH is not the only type of buffer and KH will actually tend to buffer towards higher pH.

Active substrates like fluval stratum lowers pH by stripping KH, thereby creating acidic softwater environment friendly for plants and some softwater dwarf shrimp species.

You should monitor pH weekly though, as active substrates will be exhausted. That's why a lot of shrimp keepers will change their substrate every year or so. And fluval substrate is known to have even shorter buffering life than other active substrates.

If you use remineralized (GH only) RO water or have low KH tap, buffering life of your substrate will be longer.
