Moved the uptake pump do a different part of the sump and then let it run for a couple of hours.
This seems to have mostly fixed the problem.

Effluent is now:

Kh = Still off the top 16+
Ca = 480
PH = 6.8

So now I just need to juggle things to get it where I want.

Thanks all.

on sailfert alk its actually 2ml of water 1 drop oh kh-ind for the low resolution then multiply the value by 2

yup, and 1 ml of water is "ultra low res" .  Just remember to multiply by 4 rather then 2.

so are you suppose to test effulent differently?

Testing the effluent of the reactor gives you an idea of how well it's working.  You test it the same way you'd test your tank water.  I hardly ever test my effluent calcium because I know it will track with my alk... it has to.

as opposed to 4ml of water and 2 drops of kh-ind.

For the alk test I only use 1 ml of effluent water.  One drop of indicator.  And titrate to color change.  Read the alk value off the chart and multiply by 4.  This saves on titrate (the kit will last longer).  And I only use 1 ml for the calcium test and multiply the answer by two... I think the instructions for the calcium kit actually explain this.

Oh, and make sure you titrate the calcium kit past the purple color to blue.

Ok,
Test kits are Salifert.
Tank:

dKh = 9.6-10
Ca  = 390-400
PH  = 7.9-8.0
Mg  = 1400

Effluent:

dKh = Off the top15+
Ca  = 180
PH  = 6.6
Mg  = ?? Didn't take it.

However, as I stated previously I think the problem is caused my mypickup pump located right next to my top off hose so I think that areais mostly fresh.
I was planning on moving it tonight and seing if it improves.

wait:

what are your tank params again?

and what are the readings from your effulent?

what kind of test kits are you useing?

help me fit my head around this.

I deffinetly listen to John! Do you think I want a    Just kidding

Actually I have been able to keep the CA around 400.
It is the Kh I have a hard time maintaining. I end up adding lots of buffer.
From reading the articles, it looks like I will need to start adding kalk while using the ca reactor.
Correct?

That is what I had thought. The numbers just didn't make sense.
However, I had checked them twice and they came out the same. (for the effluent)

Thinking about it, I think I may have part of the answer, I justrealized that my top off pours right next to the pickup pump for thereactor.
So that area is mostly fresh water.
I will move my pump tonight and see what it does.

Thanks for the insight

I would listen to John. This is his area of expertice.
Also before dialing in your reactor it is a good idea to get your calcium up to were it should be. I used turbo ca for this. The ca reactor is more designed to maintain ca rather then raise it. ]]> Wed, 01 Feb 2006 15:56:22 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=10266&PID=96168&title=confused-about-effluent-readings#96168 <![CDATA[Confused about effluent readings : Kh up off the scaleCA 180 This...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=10266&PID=96166&title=confused-about-effluent-readings#96166 Author: jfinch

Kh up off the scale
CA 180

This isn't right.  Your calcium number is bad.  Your calcium value in the effluent has to be higher then in your tank.

The Kh is high because the of CO2, right?
Why is the CA so low? Because of the high Kh?

No, CO2 does not measure as alkalinity.  The alk is high because the media is dissolving and when it dissolves it releases both calcium and alkalinity.  The effluent of my reactor is normally 12 meq/l (34 dKH) and 600 ppm calcium.

I'd recheck your calcium number.
