Red Sea Coral Pro results

I am in hopes that you can assist me with a problem that I am currently facing with a new bucket of RSCP salt. I've been using the salt for about the past 6 months and love it! It has greatly improved coloration, increased growth and polyp extension of all of my corals. So, I'm by no means bashing the product.

New bucket delivered a week ago by Dr's F&S has some really low test results. At 1.026(refractometer) and at 79F
- Alk 6.5dKH
- Ca 300ppm
- Mg 900ppm

In the past I've had much higher readings, almost what is advertised on the buckets. (Never exactly though) I mixed the new bucket thoroughly when I received it. Emptied half of the contents into a second bucket, shook and rolled both halves then remixed the two together. I felt that it was a little overkill actually, but wanted to be thorough. Do I have a bad batch or something? Batch number was printed askew so its a little difficult to read but; 101120310 is what I can make out.

Any assistance would be greatly appreciated.

PS. I make up a 55gal Brute can of RODI water and add the salt to the container. Its mixed by a large powerhead and a heater is used to heat the water. Typically I add 18 cups of salt to the container.

my 55 gallon drum took 34 cups to make 1.024... I got milk

I am trying to make heads or tales of this. Are you saying that you had a 55 gallon drum of water and you mixed 34 cups of salt?

So if we take the 1/2 cup per gallon range, that would be around 28 cups of salt. I know that would be a little low and need more, but 34 cups does not sound far off at all.

I have posted before, but I have yet to see this salt cloudy unless I add a buffer to it when I mix.

I may be a bit off but, the difference seems quite far off...25% off more or less. Correct me if I am wrong...I have been wrong many times before.

From my experience the 1/2 cup per gallon gets you closer to 1.020 if not a little lower. So I would say that your 34 is about spot on. I know it always takes me a lot more than 1/2 cup a gallon.

Hi,
I’m sorry for the late response, I was out and about.
In order to get to the salinity to 35ppt you will need 38.2gram per liter.
If you are using kitchen measuring cups it’s about ±0.4 a cup per Gallon.
For 55gal it's about 22-23cups.

Bill, 18cups for 55gal sound to me a bit low, which can explain the low parameters, BUT I sent you a PM, to further look into it.
[it seems like all the elements are diluted with the same factor]

Mark, 34 cups for 55 gal sounds to me way too much, which can explain “the milk”, overshooting the salinity will cause precipitation.

Make sure you test the salinity with a calibrated refractometer.

All the best,
Aviad

Thank you for your reply. I think I figured out the low values, human error. I think its best for me to not to attempt to read a refractometer at 2am after working 13hrs.

I will retest the next batch, hopefully with a fresher set of eyes. My apologies to you. As stated in a previous post I really like this product and am having great success with it. As far as the volume of salt per gallons in my container, the container may be off. I haven't attempted to get an accurate measurement of its volume, just what the label stated when purchasing it.

I'll update this as soon as I make the next batch!

Hi there!

I have just bought a bucket of RED SEA CROAL PRO SALT. I want to mix a total of 106 liter of RO water for my next water change of my DT. so if you said 38.2 gms of RSCPS to a liter of water then it means I have to measure about 4 kilos (4049.2 gms) of red sea coral pro salt? just to re-affirmed if this is correct.

by the way, normally the temperature here is around 25 to 28 degree centrigate, so will this be over your said 20 degree centrigate water temp for mixing the salt without getting cloudy water? IF SO, THEN i DONT KNOW HOW CAN i LOWER DOWN THE TEMP , BY ADDING NORMAL (ICE CUBES) but not made from RO WATER?

Lastly, I always check for the salinity to 1.026 specific gravity in my previous other brand salt mix. so, I havbe to do teh same or just saying that I weight about 4 kilos RSCPS even without checking the sp. gr?

please help as I am about to made water change this saturday.

thanks in advance

cheers,

No responding????

Hi,
4049.2 g is the right weight.
I strongly advise to always check salinity, regardless of what you did to mix the water.
What if the scales gives a wrong reading one day, there are a lot of other “what if’s” , it takes 5 seconds to check the salinity.
For a temp. like yours, to mix the water quickly and use them right away.
Sprinkle your salt and add the amount over a couple of minutes and use a strong pump.
It would take about 15min. for it to dissolve.
Over mixing will cause precipitation.
Hope I helped.
