Help with Calcium reactor settings...

[Jim Barry]

I bought my calcium reactor a couple of weeks ago and I am having trouble getting the proper settings.

Can you have a calcium reading that is too high and will it harm the corals or fish?

PH in tank = 8.35
PH in effluent = 6.7
Alkalinity = ok (don't know the exact readings)
Calcium = 600 ppm
Specific gravity = 1.023
temp 78-80

I have been adjusting my bubble counter and effluent flow, where my effluent flow rate is about 80 drops per minute and my bubble counter is 60 per minute and my effluent is running at about 144 drops per minute.

What should my bubble counter and effluent drops per minute be?

Thanks

Jim
