salt not completely dissolving

I was thinking about getting two nano koralia pumps and a wavemaker, do you think that would be enough for my tank?

 

depends what corals you want to keep. i think two nano koralias are a bit lacking.

 

salt not completely dissolving happened to me what I was setting up my tank. There are a couple things I can think of that are happening.

1) There is way to much salt in your tank and your hydrometer is broken
2) It is just the sand from the bottom of your tank floating around
3) Or, which was the case for me, the salt is bad. The salt that I had used I got from a friend who quit the hobby. The salt was kind of clumpy when I was putting it into the tank, but I just broke it apart and thought nothing of it. It did not dissolve and I had to empty the tank and start over. It was my first lesson learned and I was barely 12hrs into the hobby.

 

Did they mention they had sand in there yet?

 

I would get bigger Koralias, I run 2 Koralia Nanos in my 10 gallon Nano, with a HOB box filter...

 

Depends on what you are keeping as well. Different critters like different flow.
