Seachem Reefsalt Review

[kwirky]

I've mixed at least 15-20 buckets of the stuff at the store. I use it if we run out of reefer's best. It takes FOREVER to mix and sometimes doesn't fully mix if the salt was added while the water was cold. Sometimes the cloudiness doesn't go away even 12+ hours later. The alkalinity and calcium is pretty good though, usually testing in the recommended ranges.

We have lost livestock here and there, nothing major, because of the slow mixing speed of this salt. When you've got 200-300 gallons of water to change in a single day and only a 50 gallon mixing basin this is not the best salt to use. That's why we prefer reefer's best over the seachem even though it's like double the cost (and cost is important when you've got profit margins to maintain). Overall the gripe for this salt is it doesn't mix fast like oceanpure pro or reefer's best.

If it's given a full 24 hours though it's not bad. The price is great for how it tests and I think reefers who have the time to wait for the stuff to mix can find it a good quality salt for the price. We trust our corals with this salt over oceanpure pro.

I tried it about 2 years ago and won't use it again.

I just went through my first 2 buckets of SeaChem out of curiosity. At a salinity of 1.025 I measured the Calcium to be 600ppm, Alk 10dkh, and Mg 1275. I used both Salifert test kits and Elos test kits and sort of averaged these amounts.

The Salt does take a long time to mix but I always like to have a 20 gal garbage can of ready to use saltwater so I always have a full week to let the new saltwater mix before I even use it.

While I've been using it I havent had to adjust the Calcium in my tank because the salt mix always shoots it right back up each time I do a water change. I've also experienced my sebae anemone spawning 4 times in the few months that I have been using this salt... although I dont think it was the salt to blame. Also, nothing has died while using it.

Use it in about 40 plus maintenance tanks of mine, almost all are premixed from the last visit.

Works great, requires little testing as it has great consistency, but does take a while to mix.

Used a lot of salts, and I like seachem b/c of price, avail, and consistency.

everytime calcium tested above 500 while alk around 5 to 6. what's wrong with this company anyway?

Been using it from the start and have great results.

But it does take a while to mix and clear, but I normally do it a day in advance anyway...

Wow. Lots of replies!

From the looks of things there's some pretty significant inconsistencies and several posts have confirmed the high Ca concern that seems to be getting blown off by Seachem.

I guess I'll go with Reef Crystals and add some Ca upon mixing.
