Fluctuating PH

[JD'sReef]

Since I have been dripping KALK mix (1TBS pr Gallon), I have noticed one of my BTA's is staying shriveled up. During the morning hrs, when the MH fires up, the PH is 8.2/8.3 range. However, seeing as though my Kalk is dripping all day, when the lights finally go out around 10pm, the PH is about 8.4/8.5. The green BTA is also located directly under the 175MH and I am sure its location has something to do with this. My small Rose BTA is in a different location of the tank and does fine all day long.
-My question is how do I reduce the change in PH?
- Also, is there is make shift type of system that will automatically turn on the Kalk drip system in the evening and off when the lights turn on?


Thanks,
J.

How long have you been doing this ? IMO that pH is fine.

Since I started dripping Kalk mix about 1month ago.
I like doing this drip because the water Params stay more consistent (currently at KH-9.0dkh, CA - 430ppm), but i cam not figure out why that one anemone is getting pissed.
Out of town for a bit though so I guess i will have to let it be till I get home.

I'd see how it goes, but maybe look for other causes.

Are you using a pump with the kalk ? If not, you could try an aqualifter dosing pump set on a timer to drip only at night.

I use a LiterMeterIII and have no problems at all. It doses B-Ionic calcium and alkalinity equally on a 24 hour cycle. You set it and forget it. It is a little pricey but well worth its weight in gold. Seems to keep the PH right at 8.2 all the time.
