Reef salt parameters off
Anyone else having problems with their parameters not meeting what is on aquaforest ticket? I mix up a 5 gallon bucket of salt water and tested it. It showed 481 calcium and 7.3 alkalinity. On the ticket it said it should be 425 calcium and 8.0 alkalinity. Both of these were tested what Hannah checkers. This is Reef salt

Yes this seems to be a common complaint. There's a big thread on it here, and it comes up multiple times on their facebook group.
My first bucket of probiotic was completely off from the ticket it came with (multiple test kits, multiple refractometers w/ 2 different calibration fluids). My next two buckets (Reef Salt then Probiotic again) matched the ticket almost perfectly. |

Hello,
If Ca is 481 ( I am sure that not) but if it is so difference between 481 and 425 is 56ppm when you will make 10% water change Ca could rise 5,6ppm - your corals will consume that in 1 day What is your salinity? |

i see nothing really worth to complaint about ?? AF specifies the salt as Alk 7,7..8,3 °dH and Ca between 440..460 mg/L if mixed to 35 psu Compared to what you measured, this is less than 5% of what they promise. Also there is the chance that you made slight errors in - mixing (amount of water and weight of salt used really according instructions ?) - Did you check the salinity and are sure that you measure correctly ? - Did you calibrate your hanna checkers measurement values, or do you "just believe" what your checkers tell you ? rgds Martin

Beware the Reefsalt,got a bucket in to get more aggressive with some water changes,I been using AF Probiotic.
Because of a UK forum thread i thought i better check it. Reefsalt: Ca 550 Mg 1550 Lot/Batch 442 |

How much salt did you mix to how much water ? RO/DI used ?

Looks like you have mixed the salt at 1.027 instead of 1.026? That is probably why the calcium is higher, but alkalinity is going to be quite low. Easy to fix though.

If two 35ppt solutions say 1.027 & the salt mix also says that,I would assume the salt mix is also 35ppt NO? |

In any event if it is that close the parameters from the salt will not change that much by mixing it so it reads 1.026. |

Yeah we're still looking at needing to lose more than 100ppm on both

Qute interesting as you did a lot to get correct measurements and anyhow the values are a bit strange
I doubt a bit the readings from the digital Refrac. 1,027 SG @28,0°C is 37,2 psu and thus quite a lot higher than the 35 psu that it should be. I also wonder a bit that the Refrac doesn't show you the "psu" reading but instead SG at measurement temperature. PSU is much easier to interprete as SG that has always to be regarded together "with measurement temperature". So it seems that your Refrak has an Offset an shows a too high value. My personal test of a batch of AF Pro Biotice salt was - 41,7g added to 1L needed to achieve 34,8 psu - CA 395, Alk 6,0°dH Mg 1385 (very accurate temp/water-Volume/density measurement, Reef-Anlaytics calibrated test kits) Did you check your test kits for Ca/Mg also to test the Fauna Marin MultiReference? This results would be the most interesting ones.

watered the mix down to 33ppt & still get 500 Ca
Aquaforest so much response i'm overwhelmed. Just keep posting pretty pics in other threads & ignore anyone with any "issues" I'm done using this brand,If they can't control their major elements who knows where the hell the minors are at. |

CA: 400, Alk 6.1 (this would explain a lot of whats been going on with my tank), Mg 1410 I only test my salt batches randomly and this was the first time I tested this batch. But this is the second batch of salt whos parameters were off.

http://www.reefcentral.com/forums/sh...ef+salt&page=3 You can probably gauge the level of response from AF in that thread to what they will respond in yours.

I'm trying AF PB mix and my SG has been a little low after mixing. I am going by weight and have a gram scale to exactly get my measurements like I did with ESV (which is always perfect). My finished mix is around 1.024-1.025 when I was aiming for 1.026.
I'm also noticing my pH dropping after my water change. Why would that happen? I keep my tank at dkh8 (auto alk/ca daily). went from ph8.0 down to 7.8 within an hour. hmmm

Im not saying that is the issue with your water or questioning how you make water but it could be a cause of low pH. I make water and agitate the water with a pump and inject air for 24 hours before I add the salt. My tank pH has never dropped from a water change. Im more wondering why my parameters are so off with this batch. I know from the last go around with this issue AF said they will QA the salt to prevent this from happening...did they?

that make sense of my first water change now. just starting AF 2 days ago, too excited. i didnt test alk/ca/mg after mixing, did a 50G water change. test next morning. Alk went down as i expected, Ca and Mg went up.(i did stopped all my alk/ca/mg dosers)
well, i was looking for a salt that have low alk, high ca and mg. at least this bucket is exactly what i was looking for. just like any synthetic salt. it's hard to have a 100% even mixed.
