High Alkalinity By Peter on 12/30/2019Peter wouldn't recommend this product to a friendThis is not going to be a good review for Reef Crystals ,, I have been using this salt from day one since I got into the hobby... I have been in the hobby a long time... "is it the best salt out there"... naw it's not, it's always been a good salt at a good price though. Lots of Reefers use it... I am now making a switch to another salt. It's ordered and will be here in the next day or 2...what I am switching to Tropic Marin Pro salt.
My last order was for 2 buckets of salt in the orange bucket... I usually order the 200g boxes...I wanted the buckets though and didn't buy the boxes this time around...the first bucket I used put my salinity in the tank thru the roof...I was told by a friend that you have to dump the buckets out ...mix them up ...then use the salt ...so I put the first bucket to the side...broke open the second bucket ...mixed it up and did another water change 2 weeks later...salinity in the tank was 8.3 before the water change ...after the water change, salinity went up to 10.3. I am not sure whats up with this, but enough is enough. I am done with this salt :(
Great stuff and cheap! By Luke on 12/28/2019Luke would recommend this product to a friendI've used this salt exclusively for years. No issues so far and everything is thriving.
Great value By Ruth on 9/19/2019Ruth would recommend this product to a friendI have been using this brand for years without any problems.
works great By Lori on 3/27/2019Lori would recommend this product to a friendwent from red sea coral pro to this. 200 gallon box for like $35 can't be beat. elevated levels. doesn't mix up as clear or as quickly as the red sea, but doesn't seem to make my tank any less crystal clear.
It works! By Daniel on 2/23/2019Daniel would recommend this product to a friendHaving an SPS dominant tank can be tricky. I have found that having a salt that mixes up to what your tank operates at is key to maintaining stability. So as long as you are one to do consistent water changes. I like color and growth. Keep alkalinity at 8.5. Calcium at 450 and Mag around 1450. With Reef Crystals, my 40 gallon water change every two weeks keeps those numbers stable along with my dosing schedule. Mixed at 1.026, my alk is at 8.5, calcium at 450 and magnesium at 1450. So as long as they don’t change their recipe, I dont intend to change mine. Only complaint I have Is the residue left behind in the mixing container. Seeing that many have had success even with the residue, I dont see it as a negative factor as long as that residue is left in the container. Mix for 20 hours minimum before water change. Don’t think I will ever go another route.
Works well By Greg12 on 9/24/2018Greg12 would recommend this product to a friendBeen using this for quite a while. I like the box vs the bucket as I have many buckets. Good value and the water is nice and clear after mixing.
Great salt, but it has a residue By Scott on 8/6/2018Scott would recommend this product to a friendI've been using Reef Crystals for quite a while and it's served me well. It does leave a brownish residue in the mixing container if left for more than a few days, which is why I've knocked off a star, but it seems to test out ok, and it works well. I just can't help but wonder what the leftover gunk is...
Instant Ocean Reef Crystals By vapor160 on 7/9/2018vapor160 would recommend this product to a friendJust recently switched over to this product. I am getting great results with this mix. Steady parameters on each water change.
My tank is thriving! By The Reef Rocket on 6/29/2018The Reef Rocket would recommend this product to a friendBeen using this mix for years.. 20% water change every two weeks.. I never have problems and my levels stay consistent all the time.
GREAT By Brandon on 5/31/2018Brandon would recommend this product to a friendmy calcium stays at 450ppm, Magnesium Stays at 1350ppm so thats 2 things i dont dose for. Over all GREAT salt. does take a few to get it mixed right. but never had cloudy water over it.
Decent salt mix By Neal on 4/22/2018Neal would recommend this product to a friendI habe used Io and Reef Crystals in the past on my reef tanks. RC worked well for years and I love the price. I started having issues with really high alk 14 dkh and brown water wirh newly mixed saltwater and 0 tds RODI. 3 buckets in a row had this issue for me and LFS. Maybe just a bad batch but I stopped using it after that. Considering trying it again to fill my new reef tank. Gave it 4 stars becuase of the years I used it with success.
Great product By Chicago reefer on 3/3/2018Chicago reefer would recommend this product to a friendI like this salt and have used it for years. It mixes quick, is not clumpy and I get good results using it.
I have never added Mg to my tank and this is the only brand of salt I have ever used. My Magnesium is at 1700. I check it regularly and do a 10% wc weekly. Is this a defect in the salt? My specific gravity is consistently kept at 1.025. The side of the box says at 1.026 it should be 1345. I can't help but think this is why I keep losing snails and crabs. What can be done to lower Magnesium?
Question posted on Nov 22, 2017 1:30:00 PM
There are claims that Reef Crystals can be high in magnesium and by switching to a salt like Red Sea or how you will see more consistent elemental levels. Lower magnesium will just take time. You can do a couple of water changes that has more moderate magnesium levels, but it may take a few to get the levels down under 1400. I would suggest looking into the blue buckets of Red Sea Salt.

What do you reccomend I use to mix the salt? I'm thinking of using a brute 55 gal trashcan for mixing in. Also how many watts for a heater to heat the newly mixed saltwater. Thanks.
Question posted on Dec 1, 2016 7:20:00 PM
Hey, great question! Generally any untreated plastic container is fairly safe to mix saltwater in, but many plastics will leach some amount of phosphate into the water over time from the plasticizers. #2 HDPE and #5 Polypropylene without added chemicals are usually considered the safest and best for reef purposes. The Brute trash cans should be totally fine to use and are a popular solution in the reefing community. Have a great day!
