Alkalinity too high! Help !! :(

Jonathan blackwood · Jul 2, 2016

New road bump I came across in these last few days. My alkalinity has been raising slowly and now it's up to 13+ ... And I don't know why?? Here are the parameters of my tank.
Mag-1100
Cal-380
Alk-13+
Phos-0.0
Ammonia-0.0
Nitrite-0.3
Nitrate-0.0
Salt-0.24
I know my mag and cal need to come up so I'm dosing daily

and I'm guessing that's why some of the sps has been loosing a little color here and there. Too low on the nutrients. But my main concern is how to lower the alk, without lowering my PH. ?? My tank is a Redsea max 130d with prime led .

Correct your mag 100/ppm/24 hours and your alk may stabilize as well as bring your SG up.

Please list the dosing products.

Using a pH buffer?

So all my frags started to pale and I lost 2 of my best ones due to RTN

..... But I removed all of the remaking drags back to to mother tank and they seem to be gaining there health back

and so the tank has been bare with just rock now and 2 fish. And I've been dosing calcium and magnesium every day. Now my parameters have started to level out

back to the normal range again
