 |  First Water Change
well I did my first water change and it went pretty well. I mixed the water (RO) to add in a 33 gal garbage can I purchased just for water changes. I put in a small pump (Rio+ 2100), heater, and added salt mix. I tested the sg and it was the same as my tank (.0124). When it was up to temp, I did the change. The next day my sg was (.0126). Why the increase? Was the salt mix not completely dissolved? It appeared to be. just curious. |

What I do at every water change , is I leave maybe 5 gallons or so out of the tank, let the newly added water mix in for a few minutes and then test salinity. Seems like sometimes the last few gallon need to be just plain RO water. I have done that for 5 years and my salinity never jumps up after a water change. So, test the tank salinity right before adding the last few gallons of new SW. | |

It does take time for the salt to dissolve. You can't take a reading right after you mix the salt in the ro water. Though, some salts dissolve faster than others. | |
