Just did my first water test... A little confused.

You can use Kalkwasser to bring up your PH too, that is a bit more natural and a cheaper alternative. Rather than having to use fresh salt mix and fresh RODI water.

It being only a 29 gallon tank, I'd do more like a 50 percent change.

doing a wc will raise your ph up a bit, but the best method is to get it at the source. Low alkalinity leads to low and unstable PH. simply add baking soda. Add a teaspoon of baking soda disolved in some tank water once a day until the ph is up to 8.2 or 8.3

baking soda raises alk only. baked baking soda raises ph and alk. Low ph is typically poor aeration and or high co2 levels in air around tank.

I don't have the link but use the reefcalculator to find your best additive and how much to add. I would recommend a two part like b ionic. Kalk is nice but far from a perfect science and if messed up can cause major issues. Ph swings alk overdoses precipitation issues.

For now don't worry about ph toooooo much right now. Concentrate on stabilizing your alk Cal and mag. Then when you have those parameters in check and somewhat stable see where your ph is at. Ph is def important but its more an indicator that something else is wrong. IE low alk poor aeration not enough turbulence at surface etc.

Oh and when you mix your salt for water change mix it high. Maybe around .030. That will start bringing your salinity up. Or you can mix at 026 and just too off with saltwater till salinity raises
