Tested Alk -7, calcium- 300ppm. May explain some coral issues. Waiting on PH tester and calcium delivery. Currently making Alk using Randy H recipe.

Alk at 7 shouldn't harm anything, calc at 300 will, bring that up to 380 min, i like 420 - 430 as it gives some wiggle room. Don't do it all at once though, bringing it up to 380 should be over a couple of days, do roughly 50ppm per day at most, spread it out.

 

[MadReefer]

I always thought if Alk was low so was PH. So am concerned about all 3. Will be a few days before PH meter arrives.

 

[art13]

My alk is at 7 right now, my ph is 7.84, and travels anywhere between 7.65 - 8 with no issues.

I had my dkh down to 7 without harming my pH (between 7.8 and 8)

I would bring those numbers up but like mention do it slowly. I aim for the following (not sure if those are good numbers or not but my corals are doing ok)

Cal - 450
Dkh - 10
Mag - 1390

 

[art13]

Tank dkh can be anyplace between 7 and 12 and be fine, calcium between 400-450, mag is fine as long as it's over 1200 or whatever sea water is, after my battle with bryopsis my tank has been sitting anywhere from 1600-2100ppm mag.

Mark @MadReefer , have you tested after you did a water change?

 

[MadReefer]

Marcus, I have not.

Mark, don't worry about alk and its impact on pH. Just maintain alk and your pH will be controlled by the CO2 in your tank.

I screwed up. Messed up dosing calcium and now its 610ppm. I am preparing now for a water change.

Ouch that is a big jump. Hopefully you don't harm any of your corals. Keep us posted.

Mark what salt mix do you use?

The reason I asked about what salt mix do you use if cause if you were using Instant Ocean a big water change will bring Alk too high and it will make things worse....As I've told you by text I thing you'll be ok and tha Calcium will only precipitates.

Looks like i used the wrong measuring spoon. Used a table spoon instead of teaspoon.

I just researched and supposedly it has same Alk level as Instant Ocean, just be careful not to do a big WC.

Did you do you calculation based off your numbers before a water change or after? Also how soon after a water change did you test? I prefer to do my testing about 24hours after a water change to let things even out. But if I do it sooner I do no sooner than 10 to 30min after a water change

It happens. When I first started testing I was reading the numbers wrong.

 

[MadReefer]

Water change will be done tomorrow. Still mixing salt.

How are things looking so far?
