no, that was my short-hand for "calcium reactor." Most people choosing to use either a Ca Rx or to dose a 2-part supplement for maintaining Calcium, Alkalinity, and Magnesium.
 
My Reef Crystals has been coming in at:

Ca=375
Mg=990.

Just ordered Tropic Marin Pro Reef from Saltycritters, but won't be able to continue this, shipping is just too high.

I just did a water change with my TMP and my cal was 400 but my alk was 9

not sure whats going on there
 
I have not seen any info on Sybon salt.

Gdubb, I'm not sure there is a problem there. Maybe a little test noise.

Inj, I'll have to agree with Randy in that you may not be mixing to 35 ppt or 1.0264 They both seem equally low. When you mix at a higher salinity, you get more cal, alk and mag in your mix. :)

We've covered this before!!:mad: MORTON'S is the best!!

I agree its a pretty balanced salt mix at 1.026 heated 78F. Its dirt cheap at your local Jewel what more can you ask for?

Cal 420
Alkalinity 11
Magnesium 1340

I am using a Elos cal and alk test for the first time so I might be missing something on that. The display water tested the same alk

What exactly do you mean by "noise" though?

thanks
 
All of our hobby grade kits have a little margin of error depending on user error, contamination or simply just drop size of reagents.

As careful as we may be it just can not be avoided.

We should expect a little +/- in all of our kits within reason. :)
 
I have a question, at what point does salt precipitate? I have recently switched from salt brand X to Oceanic salt, the first three batches have precipitated leaving my mixing container, pump and heater coated in a heavy white powder. I let the mix settle for a few days to clear then test it @ 500+ Cal, 6 dkh Alk, Mag 1320, all tests were done with current salifert test kits, Mixed @ 1.026 with calibrated refractometer, RO/DI water @ 0 tds. What gives???

Are you adding water to salt or salt to water? You should have your fresh water ready and add salt to it to keep it from precipitating.
The same way i have been for 14 years,, adding salt to a container of RO/DI water, precipitates before getting to reef levels, i am not going over 1.026 then back.:confused:
 
The exact point at which precipitation occurs will vary depending on the temperature of the water, the salt being used, and probably a few other factors. I'm not sure whether you're seeing precipitation or maybe just some impurities.

The alkalinity number you posted seems a bit low for Oceanic. How was the refractometer calibrated? RO/DI water doesn't always work well.
 
I have had a good layer of brown covering my salt mixing container with reef crystals. Haven't for a while now.

I added a couple of teaspoons of pH buffer to the saltwater I was mixing up once and it made the saltwater precipitate big time. By chance add any buffer?

I calibrated with 35ppt calibration solution, 0 tds Ro/di is the water used for the mix, well there is a lot of impurities:confused:

Nothing added, and the brown slime and AS's lack of a good explanation and recent inconsistent batches is why i tried the switch:(
 
Hmm, I'm not sure what happened, then. Warmer water can cause more precipitation, but that's unlikely to be an issue. I haven't used that product, so I can't say much. Does the precipitate fizz in vinegar?
