Need help on KH and Chaeto

[waime]

Hi hi,

My tank is low on KH (carbonate hardiness). May I know how to bring it up, please?

Also, I've gotten some chaeto which I placed it in the sump with 24/7 12w white light shining at it but over the past 2 weeks the volume of the chaeto is getting smaller and smaller.. I know some bros here their chaeto are growing and they are able to harvest it to be sold or given away free. How did you guys do it?

Cheers!

Don't run your cheato 24/7! best is to run them on reverse photo period in your sump.
