I'm so tired right now, that I don't even have any smart a$$ comments to hurl at you guys.

IO mixes at around 1200... so 1150 with not dosing sounds about right. Ever thought about changing salt? You should start a poll on peoples favourite salt. :lol:

Gimme a moment, let me go look at my batch numbers first and I'll get back to you :wink:

Not for a while though, I picked up two 200g boxes a while back and that will last me some time.

Tested today's levels, actually slightly overshot, currently Mg at 1400ppm. (aiming for 1350ppm) I think I overestimated my total water volume.

Next WC in a week and gradual lowering should take care of that.

Now aiming to get my Alk back up, it's at 7 dkh. Will hope to get that around 8.5 then I will get the Ca up, but not before a lights-out soon, as I'm battling some cyano problems. I have Chemi-Clean but I'm saving that as my last option.

Stable alkalinity will help w cyano.

Should I let it stay at 7.0 for now then?

From what I understand, you should try to aim for 8. Gives you a bit more room for swings. Currently I am running between 7.3 and 8, still trying to balance it out by tweaking the doser... 7 weeks on.

7 is a bit low unless you're doing full Zeovit or some such thing. Figure out where you want it, get it there, and get it stable.

I raised it from 6 to 7 two days ago, and my pH climbed to an alarmingly high number, only steadily lowering since last night to a more acceptable reading. Should I continue to raise Alk slowly to avoid a pH spike? I was told that 8.5 is the number I should shoot for, yes?

What type of salt are you using for water changes? May be able to boost the magnesium by using RC instead of IO for instance instead of dosing.
