You can do a water change with Fritz salt in the red box. It’s there high alkalinity versionWhat products are available to raise alkalinity but nothing else?
I currently dose all for reef manually once a day, it’s worked well for me until now. I can’t say I’m the best at testing regularly, but my last testing showed a drop in alkalinity but my other elements are at a level I’m ok with. I have Reef Builder by seachem which I’m using to get alk back up slowly but I was wondering if there was another product that does the same?
