Monitoring PH levels in the sump or coming from the Calcium Reactor

[jeemann99]

Which one would you monitor if your PH monitoring system can only monitor one.

The Sump or the water coming from the Calcium reactor?

If it is the reactor it should be 6.5 approx.

In the sump returning into the tank should be 8.3 approx.

Which one would you monitor and does it matter which?

With a PH f 6.5 the probe would shut the selinoid off on the co2 therefore the reacter would stop reacting. If it has a selinoid on the co2. I put my probe by the return pump for my sump

 

[jeemann99]

so should I put my probe for my Milwaukee into the sump or shoudl I measure ph coming from my reactor first then have it overflow / drip into the sump?

I always measure the effluent coming from the reactor.

Ultimate Reef - What do you keep your ph at coming from your reactor? and what do you aim for in your tank?

 

[jsbzmcdaniel]

The PH in the effluent is 6.6. I have not monitored tank PH in three years. Last time I dropped the probe in the tank (3 months ago) it was 8.3.

Hope this helps

thanks

My tank right now is 8.3, but my effluent is 8.1. Any suggestions how to get it down?

You need to test your Ca & Alk to see where you are at in the tank. A Ca reactor is not meant to raise or lower CA/ALK but rather maintain it. If your effluent is at 8.1 you need to increase the CO2 and possibly slow the effluent rate down. What do you have it set at and how long has it been running?

I agree with getting some test results, and I agree with what you need to do, that what I suggested. Let the water get staurated by slowing down the effluent return.
Did you find anything out from Knop?

Take a small cup with a handle on it.Like a babys first cup.Drill a hole 3/4 the way up.Hang it on the inside of your sump. Put your probe in and drip your effluent in.My efflunt is at 6.3 Thats the only way I could get a good Calcium level.

Also drip close to the skimmer.
