i have heard baking soda will work or kalkawasser just never used this product i use the red sea  foundation to dose for alk cal and  mag  it alk just stays any  hlp would be appreciated thx all15F16084-2CB0-4036-A445-DDC66278F7AD.thumb.jpeg.e0c1f694a450417a1fdb534f6b738af4.jpeg06611189-3131-4523-910E-BABAA1E33249.thumb.jpeg.ebae608b4eb7f0afee5caa594d6ab8db.jpeg048AC8C8-D289-4F6F-ADE7-4B4A25193DD7.thumb.jpeg.401a0a2e1c1e40f9f93b5607ac68ab3e.jpegB045D83F-071F-454D-8AFA-56B70483853E.thumb.jpeg.41f49d566762cd20f4c28f695e393ce9.jpeg4E61A9A7-9719-4E93-8C51-58083BEF7A26.thumb.jpeg.1b03c24ae71bfc2853c91d20bc5cd284.jpeg

The easy solution is to not try to raise your alk to 9.

It is unnecessary to go that high, and can even be harmful, if your nutrients get low at any point.

Importantly, it is just difficult to raise your alk that high (in many systems) when dosing 2 part because of precipitation. (It is easier to run higher alk with a Ca reactor.)

Keep your alk between 7.6 and 8, where I keep mine, and you will be much happier!

Ok thx Andrew  I was going off of a brs YouTube video  that said it would hlp grow 70%more coral growth at 9 dkh I'm at 6.7 but drops 0.2 and 0.8 daily  

 

anyone have cal reactor for sale ☺ i would like to try that if not I can go buy from brs

I would take what BRS says in their videos with a grain of salt. 😆 There is NO way that my corals would grow 70% faster if I raised my dKH from 8.0 to 9.0.

I've seen lots of people try to raise their alk in order to grow coral faster, only to end up with RTN and burnt tips because they let their nutrients get low while increasing alk. High alk and low nitrate/phosphate is a recipe to kill your sps.

If I were you, I would set up a doser and have it dose 10-12 times per day. That will keep your alk nice and steady. I dose equal amounts of ATI Essentials Pro 1 and 2 this way.

I also dose Kalkwasser at night in order to help keep my pH up, and this also helps to maintain my alk.

Alternatively, you could get a Ca reactor, but then you might find yourself struggling with keeping pH up. There are tradeoffs with every approach.

I keep my alk right around 9 because I hand dose and when I’m away for a week there’s still pretty if bicarbonate. Like Lexinverts said if you keep adding more it will precipitate.  There’s an inverse relationship. If you increase your alk your calcium will drop and if you increase your calcium your alk will drop but coral is more sensitive to alk shifts. One way to get a higher alk is to increase your magnesium. I tend to keep mine on the higher side. Magnesium acts to fill the water column so calcium and alk can’t bind. 
Lou Ekus did a great talk about this process:

I use the Tropic Marin All for Reef and it’s worker well for me so far.  The downside is it is all in one so it’s difficult to tweak individual nutrients. I also add about an extra half teaspoon of the magnesium powder and that has kept things stable.

That was a great talk by Lou.   I’d completely forgotten about it. He really makes it understandable!

Yeah it was one of the better talks as reef chemistry Can really be confusing but he provides you with enough information to understand how to adjust your parameters.
