Does Carbon affect KH levels?

[Emma01]

Hi All.
I’ve started running Chemi-pure elite for nuisance diatoms (it does seem to work) although I’m wondering wether carbon/chemipure affects/alters KH levels I’ve been running it for about 3 weeks and my KH has gone down to as low as 7.6.
My KH yesterday 8.3 after W/C
Today 8.1. Both Tests done at same time. Significant drop since yesterday???
Thanks all.
Emma. Xx

so chemipure is gfo with carbon, gfo will drop KH

Likely consumption has increased. Water clarity has a lot to do with increased light and better overall quality for coral health/growth. That's my assumption when this happens to me.

Would it be better to remove the Chemipure and use as required rather than running all the time?
Thanks Emma

I prefer to run my alk in the high 7's so me personally would not do anything.. If this is a new tank I would not be trying to use gfo or carbon at all though and let the tank do its thing.

Hi the tank is about 3 years old.
I’m only using the carbon for diatoms, it seems to work . Shall I leave the gfo in the sump then or remove you think?

If your seeing good results then no need to pull, a little lower alk is fine as long as it stabilizes
