I have a 125 gallon tank, I am currently using ocean water from the bay
near my house. For evaporation I use purified/filtered
well water. Filter is a wet dry and a Magnum 350 canister, Magnum 250
for vaccumming substrate which is a crushed oyster shells 3" deep. I'm
using Seachrem's Reef Fundamentals and Reef Complete supplments twice a
week according to directions. My current readings are
NH3 0.0 ppm
No3 0.0 ppm
No2 0.3 ppm
Po4 0.0 ppm
Fe 0.0 ppm both chelated and non-chelated
PH 8.3
KH 125ppm
CA 0.0 ppm or least it's not registering with a Hagen Master test Kit.
What would be the best way to get the calcuim it up to 450-500 ppm
and at what rate should I be increasing it?
I going to convert from a fish only tank to reef.

Hi Mark,
It's not possible to have sea water with no CA, you
don't mention the SP ? is there a river running into the bay nearby? if
there is you could be collecting fresh water, but more than likely you
have a bad test kit, you should not be reading any Nitrite either. You
say your Nitrate is zero?, have you got an algae problem or is it anew
tank? if it isn't a new tank with your filtration system you should
have a fairly high nitrate reading, that type of filtration is a
Nitrate factory in salt water.
regards,
unclenorm.

as for the CA as I said either the test kit is bad as you mentioned
or I did the test wrong, it said to add drops to a vile of water,
which I did
and then add the drops from the second bottle and I should get a pink
color, then keep adding the second bottle drop by drop till water
changes to blue, now I did see blue as soon as I added the drops from
the second bottle after it turned pink I just didn't see it turn the
whole vile blue only the drop changed as it touched the pink solution.
So i may have read that test wrong and need to re-do either way. As
to the water no it's not a river running into it, I am on the eastern
shore of Virginia and get my water from chincoteague bay, which is full
salt water, my salinity is 1.026 at 79 degrees F. I've been told
that too about wet dry filters tend to be nitrate breeders, But i've
had the system up and running for 4yrs here in Virginia, have a
chocolate star fish, and four damsels along with 22lbs of live rock.
but regardless of my tests I was looking for what is the best method to
add calcuim, and what increaments it should be added at , don't want to
shock the system.

Unclenorm,
I re-did the Ca test and had it confirmed by another person, we got the
same results 120 ppm so now I need to bring it up to 400-450 ppm.
As to the Nitrite at 0.03 I re-did that one as well it's 0.0 ppm

You can buy various preparations to raise your Ca, the most common is
to use lime water (kalkweiser) as top of, but do it slowly otherwise
you get precipitation and other problems. I'm still puzzled at your
lack of Nitrates, do you have a DSB or a well stocked refugium ?
regards,
