alk vs salinity?

[146clark]

Has anyone ran a successful sps dominate reef while keeping a salinity of 1.023? The reason I ask is because I'm running a zeo system and not a fan of the rbs so I use h20cean at a salinity of 1.023 which gives me my parameters to the one needed for zeo. My tank is running with just the basic zeo system and has livestock no corals. I read most acro can dwell in a salinity of 1.023-1.026. But before adding sps just wanted to here what other think or have done. Thx in advance

which parameters exactly is this giving you?

Don't use salinity to keep track of parameters , if you must use a different salt or do other things to get your parameters where you want them.

Agreed, but I still want to know what the target "zeo" parameters are. I can't come up with any argument to deviate from 1.026 ever, so let's start this from the beginning

[146clark]

Zeo parameters are dkh of 6.5 to 7.5
Cal between 400-450
Mag between 1250-1350
Potassium 380-400

H2ocean covers all aspects except when mixed at 1.025-1.026 the dkh is 8.3-9

FWIW, I ran zeo with an alk of 9 for years. I use IO and it mixes high. I would stay with 1.026 if it were my tank.

My parameters are stabile for the last 3 months at
Dkh 7.2-7.5
Cal 400
Mag 1280
PO4 0.01
Salinity 1.023-1.024
Temp 78-79
Orp 400-430
Nitrate 0
