How well does it store?
I have tried blue bucket and Fritz blue box - blue bucket seemed very clean, Fritz blue box leaves a bunch of yellow crust even after just one mixing
Looking at upgrading to higher alk salts and it's between this Nyos salt and Coral Pro at this time
I've thought of trying the Nyos or Fauna Marin as they are very similar. I've used Red Sea Blue Bucket and Coral Pro for the last 13 or more years.
People complain constantly about Red Sea not mixing well or leaving a residue and I have never had that happen. People need to read and know how to properly mix salt. My RODI water stays at the temp of my home which is climate controlled, of 70 to 71. My RODI water might be a bit colder than that as it sits stored in 5 gallon water jugs.
I use 5 gallon Buckets for water changes and pour about 3 gallons of RODI a water at room temp in the bucket. I then pour in all the salt I need and mix using a hand held rubber long spatula type spoon.
I drop my heater in set for 79 and a powerhead. I let that mix and heat up and use it within an hour depending on if I'm cleaning the tank, etc.
Never, ever had precipitation or anything left behind. Colder water is the key. Anytime you heat water and then dump salt in, it's going to be cloudy.
Take a glass and fill it with cold water and you'll see it's clear. Take another glass and fill it with hot water and look at the clarity. When you heat water, hydrogen and oxygen molecules expand, creating micro bubbles. That's why people think salt mixes cloudy.
I'll probably stick with Red Sea. You should always before using the salt, roll the bucket on the ground for 3 or 4 feet one way then roll it the other way. Tilt it top to bottom, etc. Just make sure it's mixed. If it's a bag, then it's much easier to knead the bag and mix the salt before use.
