What temp?

EthanDouglas · Jun 28, 2017

So I have two questions regarding temperature.

1: What temp should I be mixing salt at? Is there a certain range where it dissolves faster? I know I should have it match the tank temp before I put the water in.

2: What temp should I keep my display/quarantine at? Or (better yet) what temp, in your opinion, should it be kept at? Do different temps have different affects on livestock?

Thanks

1. Its better to mix salt at the same temperature as the display tank or colder. The colder it is the harder to mix the salt. Not recommended to mix in hotter water because calcium might precipitate.

2. You want to match the natural temperature of the live stock. Common ornamental live stock are tropical, so temperature would range 72-78 or a bit more in nature, I would suggest being somewhere in the middle 75-76. You can go a bit higher too, but the higher the temperature the less oxygen is dissolved in the water.

I could be mistaken but I think cold water actually increases the likelihood of precipitation. I know it is true of supplements (IE a bottle of alkalinity supplement might snow when it gets too cold). I typically just mix at the temperature it is naturally, being in my fish room and with a hot pump circulating water. Certainly hotter than my tank water but not by much.

I am a scuba diver. Caribbean reefs run from about 70 degrees to 84 degrees. Above 84 degrees there are risks of coral bleaching. Most people run their tanks between 76 and 80 degrees.
