37 aga SPS pics

I use the pinpoint ph monitor. Sometimes I use an AP test to make sure the results are consistent with the monitor. I calibrate the thing every so often hoping that it is giving me a false reading. Its not. My ph is really 7.5

This is the fuge with a cl aqualight mini pc light. The mag 5 has a t with a 1/2" ball valve and barb fitting going to my phos ban reactor. The other barb goes to my retun jet. Not a great picture. I will try to get another one.

Mostly chaeta and caulerpa racemosa
 
What's the alk with the PH at 7.5.

Below 7 is acidic, above is alkaline, so as long as alk is OK, you corals will be fine IMO.
Very high calcium will adversely affect alk -- as I learnt recently after overdosing....

my alk is usually around 9dkh
calcium stays close to 400
what confuses me is that different tests give me different results. I have used salifert, sera, ap, tetra and natureef. Not one of these tests gave me the same results.
